By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS diff --git a/libisoburn/branches/ZeroThreeTwo/COPYRIGHT b/libisoburn/branches/ZeroThreeTwo/COPYRIGHT new file mode 100644 index 00000000..208ccb7e --- /dev/null +++ b/libisoburn/branches/ZeroThreeTwo/COPYRIGHT @@ -0,0 +1,22 @@ +Mario Danic , +Vreixo Formoso +Thomas Schmitt +libisoburn is Copyright (C) 2007-2008 Vreixo Formoso, Thomas Schmitt +xorriso is Copyright (C) 2007-2008 Thomas Schmitt +libisofs (if included) is Copyright (C) 2007-2008 Vreixo Formoso, Mario Danic +libburn (if included) is Copyright (C) 2002-2006 Derek Foreman, Ben Jansens + and Copyright (C) 2006-2008 Mario Danic, Thomas Schmitt + + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License version 2 as + published by the Free Software Foundation. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/libisoburn/branches/ZeroThreeTwo/Makefile.am b/libisoburn/branches/ZeroThreeTwo/Makefile.am new file mode 100644 index 00000000..9782ecc0 --- /dev/null +++ b/libisoburn/branches/ZeroThreeTwo/Makefile.am @@ -0,0 +1,167 @@ +pkgconfigdir=$(libdir)/pkgconfig +libincludedir=$(includedir)/libisoburn + +lib_LTLIBRARIES = libisoburn/libisoburn.la + +## ========================================================================= ## + +# Build libraries +libisoburn_libisoburn_la_LDFLAGS = \ + -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE) +libisoburn_libisoburn_la_SOURCES = \ + libisoburn/burn_wrap.c \ + libisoburn/data_source.c \ + libisoburn/isoburn.c \ + libisoburn/isoburn.h \ + libisoburn/isofs_wrap.c \ + libisoburn/libisoburn.h \ + version.h + +libisoburn_libisoburn_la_LIBADD = \ + -lisofs \ + -lburn + +libinclude_HEADERS = \ + libisoburn/libisoburn.h + +## ========================================================================= ## + + +# This is the reference application of libisoburn.

So compile in the oldest possible installation +setup unless you have reason to enforce a newer bug fix level. + +Obtain libisoburn-0.3.1.tar.gz, take it to a directory of your choice +and do: + + tar xzf libisoburn-0.3.1.tar.gz + cd libisoburn-0.3.1 + +Within that directory execute: + + ./configure --prefix=/usr + make + +Then become superuser and execute + make install +which will make available libisoburn.so.1 and program xorriso. + +For the API concepts and calls see + ./libisoburn/libisoburn.h +as well as + /usr/lib/libisofs/libisofs.h + /usr/lib/libburn/libburn.h + + + xorriso + +libisoburn comes with a command line and dialog application named xorriso, +which offers a substantial part of libisoburn features to shell scripts and +users. Its file xorriso/README describes a standalone tarball as first +preference for statically linked xorriso installation. +The libisoburn installation described above produces a dynamically linked +xorriso binary depending on libburn.so, libisofs.so, libisoburn.so. + +After installation documentation is available via + man xorriso + +Several alias links point to the xorriso binary: + xorrisofs starts xorriso with -as mkisofs emulation already enabled + xorrecord starts xorriso with -as cdrecord emulation already enabled + osirrox starts with -osirrox image-to-disk copying already enabled + +By default xorriso will depend on libreadline if the readline-dev headers +are present. This dependcy can be avoided by running + ./configure --prefix=/usr --disable-libreadline + make clean ; make +Never omit the "make clean" command after switching libreadline enabling. + + + Drives and Disk File Objects + +The user of libisoburn applications needs rw-permission for the CD/DVD burner +devices which shall be used. +A list of rw-accessible drives can be obtained by + xorriso -devices +resp. by libburn API call + burn_drive_scan() + + +A possible source of problems are hald or other automounters. +If you can spot a process "hald-addon-storage" with the address of +your desired drive, then consider to kill it. + +If you cannot get rid of the automounter that easily, try whether it helps +to always load the drive tray manually before starting a write run of +xorriso. Wait until the drive light is off. +Better try to unmount an eventually mounted media before a write run. + + +Besides true optical drives, libisoburn can also address disk files as input or +output drives. The addresses of the disk files have to be preceded by "stdio:". +Like: + "stdio:/tmp/pseudo_drive" + + + Testing + +We are quite sure that libisofs produces accurate representations of the disk +files. This opinion is founded on a lot of test burns and checks by a little +test program which compares files from the mounted image with the orignals +on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff. + +This program is not installed systemwide but stays in the installation +directory of the xorriso tarball as test/compare_file . Usually it is +run as -exec payload of a find command. It demands at least three arguments: +The path of the file to compare, the prefix1 to be cut off from path +and the prefix2 which gets prepended afterwards to obtain the path of the +second file to compare. +As further argument there can be -no_ctime which suppresses the comparison +of ctime date stamps. +The exit value is 0 if no difference was detected, non-0 else. + +Example: After + xorriso ... -pathspecs on -add /=/original/dir -- + mount /media/dvd + cd test +compare tree /media/dvd with tree /original/dir : + find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \ + | less +and vice versa: + find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \ + | less + + +------------------------------------------------------------------------------ + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License version 2 as + published by the Free Software Foundation. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The CE mechanism of SUSP shall be used to +address enough storage if needed. + +------------------------------------------------------------------------------- + +System Entries Provided by this Specification + +* AA (or another name which does not disturb other co-existing SUSP protocols) + +Description of the "AA" System Use Entry + +The field has exactly the same layout as RRIP field SL. One has to expect +more data bytes than with SL, though, and any of the 256 possible byte values. +The reader shall be prepared to detect and handle oversized data. + +One or more AA fields form the Attribute List of a file object with +a pare number of components.

Readers shall ignore them if + they are not aware of updates of this document which would + assign a meaning to them. + +If any of ACL_USER_OBJ, ACL_GROUP_OBJ, ACL_OTHER are missing then the settings +from the PX field shall get into effect. If they exist then they shall override +the PX field. + +A numeric qualifier is a binary number of variable length. The Most Significant +Byte comes first. The number shall be the "POSIX File User ID" resp. +"POSIX File Group ID" as also used in RRIP PX fields. The ids of owning user +and owning group shall be taken from the PX field of the file object. + +Optional TRANSLATE entries may associate user or group names with numeric +ids to allow the reading system to remap the numeric ids. See below. +The writer is not obliged to write them and the reader is not obliged to +interpret them. + +The ACL entries belong to the "access" ACL of a file object. An optional +SWITCH_MARK entry may direct further entries to the "default" ACL which +is defined for directory objects.

By storing names (and usually wasting space) it is possible +to control permissions in a way that is portable between uncoordinated +computers as long as the human readable user/group names are present on both +sides. POSIX File ID numbers make most sense in backups which shall be read +by the same system which wrote it. +Rock Ridge can only record POSIX File Ids but not user or group names. + +The entry flag value 0x08 TRANSLATE is not a ACL entry of the hosting object +but rather a global hint about the relation of roles, names and numeric ids. +If it is recorded at all, then it shall be recorded with the first Directory +Entry of the volume's root directory. According to the description of SUSP +field ER, this has to be "dot" or (00). Other than with ER, a TRANSLATE entry +may not appear in the root of directory sub trees. + +An interested reader shall examine the Arbitrary Attributes of this Directory +Entry in order to collect a translation table. +The advised translation is: PX or AA Id number -> name -> local id number. + +The Qualifier Bytes of a TRANSLATE entry shall have the following format: + + [i] "BP 0 - Role" shall tell whether it is about a user name (role 0) or + a group name (role 1). Other values are not allowed. + + [ii] "BP 1 to BP 8 - Numeric Id" shall hold the 32 bit POSIX Id number of the + entry. This field shall be recorded according to ISO 9660:7.3.3. + +[iii] "BP 9 to End Of Qualifier - Name" shall hold the name bytes of this + entry. + + | ROLE | NUMERIC ID | NAME | + +Example: User id number 1001 gets associated with user name "lisa" + + 0x08, 13, 0, 233,3,0,0, 0,0,3,233, 'l', 'i', 's', 'a', + + +------------------------------------------------------------------------------- + +Specification of the ER System Use Entry Values for AAIP: + +The Extension Version number for this version of AAIP shall be 1. + +The Extension Identifier field shall be "AAIP_0002" with Identifier Length 9. + +The mandatory content form of the Extension Descriptor is +"AA PROVIDES VIA AAIP 0.2 SUPPORT FOR ARBITRARY FILE ATTRIBUTES IN ISO 9660 IMAGES" +with possibly two letters other than "AA" at the start of the string. +The Description Length is 81. + +The reader of AAIP shall take the actual name of the AA field from BP 19 and +BP 20 of the ER field. + +The recommended content of the Extension Source is +"PLEASE CONTACT THE LIBBURNIA PROJECT VIA LIBBURNIA-PROJECT.ORG". +The corresponding Source Length is 62. + + +------------------------------------------------------------------------------- + +Model Relations: + + Attribute List ------------- [1:0..1] ------------- ACL + [1:0..n] [1:0..n] + Arbitrary Attribute ( [1:0..1] ACL ) Entry + [1:2..2n] [1:0..1] + Component ( [1..m:1..n] AA Field ) Qualifier + [1:1..n] << one of >> + Component Record / \ \ + [1..m:1..n] Translation Entry , Name , Numeric Id + AA Field | | | + [1:1..n] [1:1..n] [1:1] + \ | / + Qualifier Record + +------------------------------------------------------------------------------- +Revoked drafts: + +There was a draft AAIP 0.0 with ER signature "AAIP_2008A".

This includes media like DVD+RW, which do not support multi-session +management on media level and even plain disk files or block devices. + +The price for that is thorough specialization on data files in ISO-9660 +filesystem images. So libisoburn is not suitable for audio (CD-DA) or any +other CD layout which does not entirely consist of ISO-9660 sessions. + + + Connector functions + +libisofs and libburn do not depend on each other but share some interfaces +by which they can cooperate. +libisoburn establishes the connection between both modules by creating the +necessary interface objects and attaching them to the right places. + + + Wrapper functions + +The priciple of this frontend is that you may use any call of libisofs or +libburn unless it has a isoburn_*() wrapper listed in the following function +documentation. + +E.g. call isoburn_initialize() rather than iso_init(); burn_initialize(); +and call isoburn_drive_scan_and_grab() rather than burn_drive_scan_and_grab(). +But you may call burn_disc_get_profile() directly if you want to display +the media type. + +The wrappers will transparently provide the necessary emulations which +are appropriate for particular target drives and media states. +To learn about them you have to read both API descriptions: the one of +the wrapper and the one of the underlying libburn or libisofs call. + +Macros BURN_* and functions burn_*() are documented in +Macros ISO_* and functions iso_*() are documented in + + + Usage model + +There may be an input drive and an output drive. Either of them may be missing +with the consequence that no reading resp. writing is possible. +Both drive roles can be fulfilled by the same drive. + +Input can be a random access readable libburn drive: + optical media, regular files, block devices. +Output can be any writeable libburn drive: + writeable optical media in burner, writeable file objects (no directories). + +libburn demands rw-permissions to drive device file resp. file object. + +If the input drive provides a suitable ISO RockRidge image, then its tree +may be loaded into memory and can then be manipulated by libisofs API calls. +The loading is done by isoburn_read_image() under control of +struct isoburn_read_opts which the application obtains from libisoburn +and manipulates by the family of isoburn_ropt_set_*() functions. + +Writing of result images is controlled by libisofs related parameters +in a struct isoburn_imgen_opts which the application obtains from libisoburn +and manipulates by the family of isoburn_igopt_set_*() functions. + +All multi-session aspects are handled by libisoburn according to these +settings. The application does not have to analyze media state and write +job parameters. It rather states its desires which libisoburn tries to +fulfill, or else will refuse to start the write run. + + + Setup for Growing, Modifying or Blind Growing + +The connector function family offers alternative API calls for performing +the setup for several alternative image generation strategies. + +Growing: +If input and output drive are the same, then isoburn_prepare_disc() is to +be used. It will lead to an add-on session on appendable or overwriteable +media with existing ISO image. With blank media it will produce a first +session. + +Modifying: +If the output drive is not the input drive, and if it bears blank media +or overwriteable without a valid ISO image, then one may produce a consolidated +image with old and new data. This will copy file data from an eventual input +drive with valid image, add any newly introduced data from the local +filesystem, and produce a first session on output media. +To prepare for such an image generation run, use isoburn_prepare_new_image(). + +Blind Growing: +This method reads the old image from one drive and writes the add-on session +to a different drive. That output drive is nevertheless supposed to +finally lead to the same media from where the session was loaded. Usually it +will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program +like with this classic gesture: + mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev +Blind growing is prepared by the call isoburn_prepare_blind_grow(). +The input drive should be released immediately after this call in order +to allow the consumer of the output stream to access that drive for writing. + +After either of these setups, some peripheral libburn drive parameter settings +like burn_write_opts_set_simulate(), burn_write_opts_set_multi(), + burn_drive_set_speed(), burn_write_opts_set_underrun_proof() should be made. +Do not set the write mode. It will be chosen by libisoburn so it matches job +and media state. + + Writing the image + +Then one may start image generation and write threads by isoburn_disc_write(). +Progress may be watched at the output drive by burn_drive_get_status() and +isoburn_get_fifo_status(). + +At some time, the output drive will be BURN_DRIVE_IDLE indicating that +writing has ended. +One should inquire isoburn_drive_wrote_well() to learn about overall success. + +Finally one must call isoburn_activate_session() which will complete any +eventual multi-session emulation. + +*/ + + + /* API functions */ + + +/** Initialize libisoburn, libisofs and libburn. + Wrapper for : iso_init() and burn_initialize() + @since 0.1.0 + @param msg A character array for eventual messages (e.g. with errors) + @param flag Bitfield for control purposes (unused yet, submit 0) + @return 1 indicates success, 0 is failure +*/ +int isoburn_initialize(char msg[1024], int flag); + + +/** Check whether all features of header file libisoburn.h from the given + major.minor.micro revision triple can be delivered by the library version + which is performing this call. + An application of libisoburn can easily memorize the version of the + libisofs.h header in its own code.

By Thomas Schmitt +Integrated sub project of libburnia-project.org but also published via: +http://scdbackup.sourceforge.net/xorriso_eng.html +http://scdbackup.sourceforge.net/xorriso-0.3.1.tar.gz +Copyright (C) 2006-2008 Thomas Schmitt, provided under GPL version 2. +------------------------------------------------------------------------------ + + +xorriso is a program which maps file objects from POSIX compliant +filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows +session-wise manipulation of such filesystems. It can load the management +information of existing ISO images and it writes the session results to +optical media or to filesystem objects. +Vice versa xorriso is able to restore file objects from ISO 9660 filesystems. + +Currently it is supported on Linux with kernels >= 2.4 and on FreeBSD versions +with ATAPI/CAM support enabled in the kernel, see atapicam(4). + +A special property of xorriso is that it needs neither an external ISO 9660 +formatter program nor an external burn program for CD or DVD but rather +incorporates the libraries of libburnia-project.org . + +By using this software you agree to the disclaimer at the end of this text: +"... without even the implied warranty ..." + + + Compilation, First Glimpse, Installation + +The most simple way to get xorriso from source code is the xorriso standalone +tarball. + +Prerequisites: +The tarball contains anything that is needed except libc and libpthread. +libreadline and the readline-dev headers will make dialog mode more convenient, +but are not mandatory. + +Obtain xorriso-0.3.1.tar.gz, take it to a directory of your choice and do: + + tar xzf xorriso-0.3.1.tar.gz + cd xorriso-0.3.1 + +Within that directory execute: + + ./configure --prefix=/usr + make + +This will produce a binary named + ./xorriso/xorriso + +which you may strip to reduce it in size + strip ./xorriso/xorriso + +You may copy or move it to a directory where it can be found by the shell, +or you may execute xorriso at the place where it was built, +or you may execute as superuser: + make install + +For general concepts, options and usage examples see + man 1 xorriso + +This man page is part of the tarball as + xorriso/xorriso.1 +You may get a first glimpse by + man ./xorriso/xorriso.1 + +It gets installed with "make install" but may also be placed manually in the +./man1 directory below one of the directories mentioned in environment +variable $MANPATH. + +The installation creates several alias links pointing to the xorriso binary: + xorrisofs starts xorriso with -as mkisofs emulation already enabled + xorrecord starts xorriso with -as cdrecord emulation already enabled + osirrox starts with -osirrox image-to-disk copying already enabled + +If you want to avoid dependecy on libreadline although the libreadline +development package is installed, then rather build xorriso by: + ./configure --prefix=/usr --disable-libreadline + make clean ; make +Never omit the "make clean" command after switching libreadline enabling. + +If you want xorriso to report a "Build timestamp" with its option -version: + make buildstamped + + + Drives and Disk File Objects + +The user of xorriso needs rw-permission for the CD burner device. +A list of rw-accessible drives can be obtained by + + xorriso -devices + +CD devices which offer no rw-permission are invisible to normal users. +The superuser should be able to see any usable drive and then set the +permissions as needed. + +The output of xorriso -devices might look like + +0 -dev '/dev/sr0' rwrw-- : 'TSSTcorp' 'CDDVDW SH-S203B' +1 -dev '/dev/hda' rwrw-- : 'HL-DT-ST' 'DVD-ROM GDR8162B' + +Full and insecure enabling of both for everybody would look like + chmod a+rw /dev/sr0 /dev/hda +This is equivalent to the traditional setup chmod a+x,u+s cdrecord. + +I strongly discourage to run xorriso with setuid root or via sudo ! +It is not checked for the necessary degree of hacker safety. + +Consider to put all authorized users into group "floppy", to chgrp the +device file to that group and to disallow w-access to others. + + +A possible source of problems are hald or other automounters. +If you can spot a process "hald-addon-storage" with the address of +your desired drive, then consider to kill it. + +If you cannot get rid of the automounter that easily, try whether it helps +to always load the drive tray manually before starting a write run of +xorriso. Wait until the drive light is off. +Better try to unmount an eventually mounted media before a write run. + + +Besides true optical drives, xorriso can also address disk files as input or +output drives. By default paths to files under /dev are accepted only if the +device represents a real optical drive. Other device files may be addressed +by prepending "stdio:" to the path. +Like: + xorriso -dev stdio:/dev/sdb ...more arguments... +This rule may be changed by xorriso option -drive_class. +Prefix "mmc:" causes a path to be accepted only if it is a real optical drive. + + + Testing + +We are quite sure that libisofs produces accurate representations of the disk +files. This opinion is founded on a lot of test burns and checks by a little +test program which compares files from the mounted image with the orignals +on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff. + +This program is not installed systemwide but stays in the installation +directory of the xorriso tarball as test/compare_file . Usually it is +run as -exec payload of a find command. It demands at least three arguments: +The path of the first file to compare, the prefix1 to be cut off from path +and the prefix2 which gets prepended afterwards to obtain the path of the +second file to compare. +As further argument there can be -no_ctime which suppresses the comparison +of ctime date stamps. +The exit value is 0 if no difference was detected, non-0 else. + +Example: After + xorriso ... -pathspecs on -add /=/original/dir -- -commit_eject all + mount /media/dvd + cd test +compare tree /media/dvd with tree /original/dir : + find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \ + | less +and vice versa: + find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \ + | less + + + File Formats + +Currently there is only one file format peculiar to xorriso : sector maps +which describe the valid and invalid blocks on a media or a disk copy of +a media. xorriso creates and reads these file with its option -check_media. + +The file begins with 32 bytes of cleartext of which the last one is a +newline character. The first 25 say "xorriso sector bitmap v2 ", the +remaining six characters give the size of the info text as decimal number. +This number of bytes follows the first 32 and will not be interpreted +by xorriso. They are rather to inform a human reader about the media type +and its track layout. +After the info text there are two 4 byte signed integers, most significant +byte first. The first one, N, gives the number of bits in the following bitmap +and the second number S gives the number of 2 KiB blocks governed by a single +bit in the map. Then come the bits in form of 8-bit bytes. +Data block M is covered by bit B=M/S in the map, bit number B is stored in +byte B/8 as bit B%8. A valid readable data block has its bit set to 1. + + + libisoburn + +xorriso is based on libisofs which does ISO 9600 filesystem aspects and on +libburn which does the input and output aspects. Parts of this foundation +are accessed via libisoburn, which is closely related to xorriso. + +libisoburn provides two services: +- Encapsulation of coordination between libisofs and libburn. +- Emulation of ISO 9660 multi-session on overwriteable media + or random access files. + +The sourcecode of all three libraries is included in the xorriso standalone +tarball. It is compiled with xorriso and linked statically. +But you may as well get and install releases of libburn and libisofs, in order +to be able to install a release of libisoburn which produces libisoburn.so.1 +and a matching dynamically linked xorriso binary. +This binary is leaner but depends on properly installed libraries of suitable +revision. + +Dynamic library and compile time header requirements for libisoburn-0.3.1 : +- libburn.so.4 , version libburn-0.5.8 or higher +- libisofs.so.6 , version libisofs-0.6.12 or higher +libisoburn and xorriso will not start with libraries which are older than their +headers seen at compile time. So compile in the oldest possible installation +setup unless you have reason to enforce a newer bug fix level. + +Standalone xorriso has less runtime dependencies and can be moved more freely. + + +------------------------------------------------------------------------------ + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License version 2 as + published by the Free Software Foundation. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

images +with Rock Ridge extensions. +.SH SYNOPSIS +.B xorriso +.RI [ settings | actions ] +.br +.SH DESCRIPTION +.PP +.B xorriso +is a program which maps file objects from POSIX compliant +filesystems into Rock Ridge enhanced ISO 9660 filesystems and allows +session-wise manipulation of such filesystems. It can load the management +information of existing ISO images and it writes the session results to +optical media or to filesystem objects. +.br +Vice versa xorriso is able to restore file objects from ISO 9660 filesystems. +.PP +A special property of xorriso is that it needs neither an external ISO 9660 +formatter program nor an external burn program for CD or DVD but rather +incorporates the libraries of libburnia-project.org . +.SS +.B Overview of features: +.br +Operates on an existing ISO image or creates a new one. +.br +Copies files from filesystem into the ISO image. +.br +Renames or deletes file objects in the ISO image. +.br +Changes file properties in the ISO image. +.br +Updates ISO subtrees incrementally to match given disk subtrees. +.br +Writes result either as completely new image or as add-on session +to optical media or filesystem objects. +.br +Can activate ISOLINUX boot images via El Torito. +.br +Can perform multi-session tasks as emulation of mkisofs and cdrecord. +.br +Can restore files from ISO image to disk filesystem (see osirrox). +.br +Can issue commands to mount older sessions on Linux or FreeBSD. +.br +Can check media for damages and copy readable blocks to disk. +.br +Scans for optical drives, blanks re-useable optical media. +.br +Reads its instructions from command line arguments, dialog, and batch files. +.br +Provides navigation commands for interactive ISO image manipulation. +.br +Adjustable thresholds for abort, exit value, and problem reporting. +.SS +.B General information paragraphs: +.br +Session model +.br +Media types and states +.br +Creating, Growing, Modifying, Blind Growing +.br +Libburn drives +.br +Rock Ridge, POSIX, X/Open, and El Torito +.br +Command processing +.br +Dialog, Readline, Result pager +.sp 1 +Maybe you first want to have a look at section EXAMPLES near the end of +this text before reading the next few hundred lines of background information. +.SS +.B Session model: +.br +Unlike other filesystems, ISO 9660 is not intended for read-write operation but +rather for being generated in a single sweep and being written to media as a +.B session. +.br +The data content of the session is called filesystem +.B image. +.PP +The written image in its session can then be mounted by the operating system +for being used read-only. Linux is able to mount ISO images from block devices, +which may represent optical media, other media or via a loop device even +from regular disk files. FreeBSD mounts ISO images from devices that represent +arbitrary media or from regular disk files. +.PP +This session usage model has been extended on CD media by the concept of +.B multi-session , +which allows to add information to the CD and gives the mount programs +of the operating systems the addresses of the entry points of each +session. The mount programs recognize block devices which represent +CD media and will by default mount the image in the last session. +.br +This session usually contains an updated directory tree for the whole media +which governs the data contents in all recorded sessions. +So in the view of the mount program all sessions of a particular media +together form a single filesystem image. +.br +Adding a session to an existing ISO image is in this text referred as +\fBgrowing\fR. +.br +The multi-session model of the MMC standard does not apply to all media +types. But program growisofs by Andy Polyakov showed how to extend this +functionality to overwriteable media or disk files which carry valid ISO 9660 +filesystems. This expansion method is referred as emulated growing. +.PP +xorriso provides both ways of growing as well as an own method named +\fBmodifying\fR which produces a completely new ISO image from the old +one and the modifications. +See paragraph Creating, Growing, Modifying, Blind Growing below. +.PP +xorriso adopts the concept of multi-session by loading an eventual image +directory tree, allowing to manipulate it by several actions, and to write +the new image to the target media. +.br +The first session of a xorriso run begins by the definition of the input +drive with the eventual ISO image or by the definition of an output drive. +The session ends by command -commit which triggers writing. A -commit is +done automatically when the program ends regularly. +.PP +After -commit a new session begins with the freshly written one as input. +A new input drive can only be chosen as long as the loaded ISO image was +not altered. Pending alteration can be revoked by command -rollback. +.PP +Writing a session to the target is supposed to be very expensive in terms of +time and of consumed space on appendable or write-once media. Therefore all +intended manipulations of a particular ISO image should be done in a single +session. +.br +In some special situations (e.g. in a file-to-file situation) it can be +useful to store intermediate states and to continue with image manipulations. +.SS +.B Media types and states: +There are two families of media in the MMC standard: +.br +\fBMulti-session media\fR are CD-R, CD-RW, DVD-R, DVD+R, DVD+R/DL, and +unformatted DVD-RW. These media provide a table of content which +describes their existing sessions. See option \fB-toc\fR. +.br +\fBOverwriteable media\fR are DVD-RAM, DVD+RW, BD-RE, and formatted DVD-RW. +They allow random write access but do not provide information about their +session history. If they contain one or more ISO 9660 sessions and if the +first session was written by xorriso, then a table of content can +be emulated. Else only a single overall session will be visible. +.br +DVD-RW media can be formatted by -format full. +They can be made unformatted by -blank deformat. +.br +Emulated drives are handled as overwriteable media if they are random +read-write accessible. If they are only sequentially writeable then +they are handled as blank multi-session media. +.PP +These media can assume several states in which they offer different +capabilities. +.br +\fBBlank\fR media can be written from scratch. They contain no ISO image +suitable for xorriso. +.br +Blank is the state of newly purchased optical media. +With used CD-RW and DVD-RW it can be achieved by action -blank "as_needed". +Overwriteable media are considered blank if they are new or if they have +been marked as blank by xorriso. +Action -blank "as_needed" can be used to do this marking on overwriteable +media, or to apply eventual mandatory formatting of new media. +.br +\fBAppendable\fR media accept further sessions. Either they are MMC +multi-session media in appendable state, or they are overwriteable media +which contain an ISO image suitable for xorriso. +.br +Appendable is the state after writing a session with option -close off. +.br +\fBClosed\fR media cannot be written. They may contain an ISO image suitable +for xorriso. +.br +Closed is the state of DVD-ROM media and of multi-session media which were +written with option -close on. If the drive is read-only hardware then it will +probably show any media as closed CD-ROM resp. DVD-ROM. +.br +Overwriteable media assume this state in such read-only drives or if they +contain unrecognizable data in the first 32 data blocks. +.br +Read-only drives may or may not show session histories of multi-session +media. Often only the first and the last session are visible. Sometimes +not even that. Option -rom_toc_scan might or might not help in such cases. +.SS +.B Creating, Growing, Modifying, Blind Growing: +.br +A new empty ISO image gets \fBcreated\fR +if there is no input drive with a valid ISO 9660 image when the first time +an output drive is defined. This is achieved by option -dev on blank media +or by option -outdev on media in any state. +.br +The new empty image can be populated with directories and files. +Before it can be written, the media in the output drive must get into +blank state if it was not blank already. +.PP +If there is a input drive with a valid ISO image, then this image gets loaded +as foundation for manipulations and extension. The constellation of input +and output drive determines which write method will be used. +They have quite different capabilities and constraints. +.PP +The method of \fBgrowing\fR adds new data to the existing media. These +data comprise of eventual new file content and they override the existing +ISO 9660 + Rock Ridge directory tree. It is possible to hide files from +previous sessions but they still exist on media and with many types of +optical media it is quite easy to recover them by mounting older sessions. +.br +Growing is achieved by option -dev. +.PP +The write method of \fBmodifying\fR produces compact filesystem +images with no outdated files or directory trees. Modifying can write its +images to target media which are completely unsuitable for multi-session +operations. E.g. DVD-RW which were treated with -blank deformat_quickest, +named pipes, character devices, sockets. +On the other hand modified sessions cannot be written to appendable media +but to blank media only. +.br +So for this method one needs either two optical drives or has to work with +filesystem objects as source and/or target media. +.br +Modifying takes place if input drive and output drive are not the same and +if option -grow_blindly is set to its default "off". +This is achieved by options -indev and -outdev. +.PP +If option -grow_blindly is set to a non-negative number and if -indev and +-outdev are both set to different drives, then \fBblind growing\fR is +performed. It produces an add-on session which is ready for being written +to the given block address. This is the usage model of +.br + mkisofs -M $indev -C $msc1,$msc2 -o $outdev +.br +which gives much room for wrong parameter combinations and should thus only be +employed if a strict distinction between ISO formatter xorriso and the burn +program is desired. -C $msc1,$msc2 is equivalent to: +.br + -load sbsector $msc1 -grow_blindly $msc2 +.SS +.B Libburn drives: +.br +Input drive, i.e. source of an existing or empty ISO image, can be any random +access readable libburn drive: optical media with readable data, +blank optical media, regular files, block devices. +.PP +Output drive, i.e. target for writing, can be any libburn drive. +Some drive types do not support the method of growing but only the methods +of modifying and blind growing. They all are suitable for newly created images. +.br +All drive file objects have to offer rw-permission to the user of xorriso. +Even those which will not be useable for reading an ISO image. +.PP +MMC compliant (i.e. optical) drives on Linux usually get addressed by +the path of their block device or of their generic character device. E.g. +.br + -dev /dev/sr0 +.br + -dev /dev/hdc +.br + -dev /dev/sg2 +.br +On FreeBSD the device files have names like +.br + -dev /dev/cd0 +.br + -dev /dev/acd0 +.br +Get a list of accessible drives by command +.br + -devices +.br +It might be necessary to do this as +.B superuser +in order to see all drives and to then allow rw-access for the intended users. +Consider to bundle the authorized users in a group like old "floppy". +.PP +Filesystem objects of nearly any type can be addressed by prefix "stdio:" and +their path in the filesystem. E.g.: +.br + -dev stdio:/dev/sdc +.br +The default setting of -drive_class allows to address files outside the +/dev tree without that prefix. E.g.: +.br + -dev /tmp/pseudo_drive +.br +If path leads to a regular file or to a block device then the emulated drive +is random access readable and can be used for the method of growing if it +already contains a valid ISO 9660 image. Any other file type is not readable +via "stdio:" and can only be used as target for the method of modifying or +blind growing. +Non-existing paths in existing directories are handled as empty regular files. +.PP +A very special kind of pseudo drive are open file descriptors. They are +depicted by "stdio:/dev/fd/" and descriptor number (see man 2 open). +.br +Addresses "-" or "stdio:/dev/fd/1" depict standard output, which normally is +the output channel for result texts. +To prevent a fatal intermingling of ISO image and text messages, all result +texts get redirected to stderr if -*dev "-" or "stdio:/dev/fd/1" is among +the start arguments of the program. +.br +Standard output is currently suitable for creating one session +per program run without dialog. Use in other situations is discouraged +and several restrictions apply: +.br +It is not allowed to use standard output as pseudo drive if it was not +among the start arguments. Do not try to fool this ban via backdoor addresses +to stdout. +.br +If stdout is used as drive, then -use_readline is permanently disabled. +Use of backdoors will cause severe memory and/or tty corruption. +.PP +Be aware that especially the superuser can write into any accessible file or +device by using its path with the "stdio:" prefix. By default any address +in the /dev tree without prefix "stdio:" will work only if it leads to a MMC +drive. +.br +One may use option +.B -ban_stdio_write +to surely prevent this risk and to allow only MMC drives. +.br +One may prepend "mmc:" to a path to surely disallow any automatic "stdio:". +.br +By option -drive_class one may ban certain paths or allow access without +prefix "stdio:" to other paths. +.SS +.B Rock Ridge, POSIX, X/Open, and El Torito: +.br +.B Rock Ridge +is the name of a set of additional informations which enhance +an ISO 9660 filesystem so that it can represent a POSIX compliant filesystem +with ownership, access permissions, symbolic links, and other attributes. +.PP +This is what xorriso uses for a decent representation of the disk files +within the ISO image. Rock Ridge information is produced with any xorriso +image. +.PP +xorriso is not named "porriso" because POSIX only guarantees 14 characters +of filename length. It is the X/Open System Interface standard XSI which +demands a file name length of up to 255 characters and paths of up to 1024 +characters. Rock Ridge fulfills this demand. +.PP +An +.B El Torito +boot record connects a boot image, which is a binary program plus some +other files stored in the ISO image, with the bootstrapping facility of +contemporary computers. +The content of the boot image files is not in the scope of El Torito. +.br +Most bootable Linux CDs are equipped with ISOLINUX boot images. xorriso is +able to create or maintain an El Torito object which makes such an image +bootable. For details see option -boot_image. +Emulation -as mkisofs supports the example options out of the ISOLINUX wiki. +.br +The support for other boot image types is sparse. +.br +An MBR is generated together with the El Torito boot record if the boot image +bears the isohybrid signature of ISOLINUX 3.72 or later. It will occupy the +first 512 bytes of the emerging ISO image and enable booting from media which +appear as hard disk rather than as CDROM. An MBR does not hamper CDROM booting. +The MBR of a follow-up session can get in effect only on overwriteable media. +.SS +.B Command processing: +.br +Commands are either actions or settings. They consist of a command word, +followed by zero or more parameter words. If the list of parameter words +is of variable length (indicated by "[...]" or "[***]") then it has to be +terminated by either the \fBlist delimiter\fR, or the end of argument list, +or an end of an input line. +.PP +At program start the list delimiter is the word "--". This may be changed +by option -list_delimiter in order to allow "--" as argument in a list of +variable length. It is advised to reset the delimiter to "--" immediately +afterwards. +.br +For brevity the list delimiter is referred as "--" throughout this text. +.br +The list delimiter is silently tolerated if it appears after the parameters of +a command with a fixed list length. It is handled as normal text if it +appears among the arguments of such a command. +.PP +.B Pattern expansion +is a property of some particular commands and not a general +feature. It gets controlled by commands -iso_rr_pattern and -disk_pattern. +Commands which eventually use pattern expansion all have variable argument +lists which are marked in this man page by "[***]" rather than "[...]". +.br +Some other commands perform pattern matching unconditionally. +.PP +Command and parameter words are either read from program arguments, where one +argument is one word, or from quoted input lines where words are recognized +similar to the quotation rules of a shell parser. +.br +xorriso is not a shell, although it might appear so on first glimpse. +Be aware that the interaction of quotation marks and pattern symbols like "*" +differs from the usual shell parsers. In xorriso, a quotation mark does not +make a pattern symbol literal. +.PP +.B Quoted input +converts whitespace separated text pieces into words. +The double quotation mark " and the single quotation mark ' can be used to +enclose whitespace and make it part of words (e.g. of file names). Each mark +type can enclose the marks of the other type. A trailing backslash \\ outside +quotations or an open quotation cause the next input line to be appended. +.br +Quoted input accepts any ASCII character except NUL (0) as content of quotes. +Nevertheless it can be cumbersome for the user to produce those characters +at all. Therefore quoted input and program arguments allow optional +.B Backslash Interpretation +which can represent all ASCII characters except NUL (0) by backslash codes +as in $'...' of bash. +.br +It is not enabled by default. See option -backslash_codes. +.PP +When the program begins then it first looks for argument -no_rc. If this is +not present then it looks for its startup files and +eventually reads their content as command input lines. Then it interprets +the program arguments as commands and parameters and finally it enters +dialog mode if command -dialog "on" was executed up to then. +.PP +The program ends either by command -end, or by the end of program arguments +if not dialog was enabled up to that moment, or by a problem +event which triggers the threshold of command -abort_on. +.SS +.B Dialog, Readline, Result pager: +.br +Dialog mode prompts for a quoted input line, parses it into words, and performs +them as commands with their parameters. It provides assisting services +to make dialog more comfortable. +.PP +Readline is an enhancement for the input line. You may know it already from +the bash shell. Whether it is available in xorriso depends on the availability +package readline-dev at the time when xorriso was built from its sourcecode. +.br +It allows to move the cursor over the text in the line by help of the +Leftward and the Rightward arrow key. +Text may be inserted at the cursor position. The Delete key removes the +character under the cursor. Upward and Downward arrow keys navigate through +the history of previous input lines. +.br +See man readline for more info about libreadline. +.PP +Option -page activates a builtin result text pager which may be convenient in +dialog. After an action has put out the given number of terminal lines, +the pager prompts the user for a line of input. +.br +An empty line lets xorriso resume work until the next page is put out. +.br +The single character "@" disables paging for the current action. +.br +"@@@", "x", "q", "X", or "Q" urge the current action to abort and suppress +further result output. +.br +Any other line will be interpreted as new dialog line. The current action +is urged to abort. Afterwards, the input line is executed. +.PP +Some actions apply paging to their info output, too. +.br +The urge to abort may or may not be obeyed by the current action. All actions +try to abort as soon as possible. +.br +.SH OPTIONS +.br +All command words are shown with a leading dash although this dash is not +mandatory for the option to be recognized.

Eventually one has to perform -commit or -rollback first. +Violation yields a FAILURE event. +.br +Special address string "-" means standard output, to which several restrictions +apply. See above paragraph "Libburn drives". +.br +An empty address string "" gives up the current device +without aquiring a new one. +.TP +\fB\-indev\fR address +Set input drive and load an eventual ISO image. If the new input drive differs +from -outdev then switch from growing to modifying or to blind growing. +It depends on the setting of -grow_blindly which of both gets activated. +The same rules and restrictions apply as with -dev. +.TP +\fB\-outdev\fR address +Set output drive and if it differs from the input drive then switch from +growing to modifying or to blind growing. Unlike -dev and -indev this action +does not load a new ISO image. So it can be performed even if there are pending +changes. +.br +-outdev can be performed without previous -dev or -indev. In that case an +empty ISO image with no changes pending is created. It can either be populated +by help of -map, -add et.al. or it can be discarded silently if -dev or -indev +are performed afterwards. +.br +Special address string "-" means standard output, to which several restrictions +apply. See above paragraph "Libburn drives". +.br +An empty address string "" gives up the current output drive +without aquiring a new one. No writing is possible without an output drive. +.TP +\fB\-drive_class\fR "harmless"|"banned"|"risky"|"clear_list" disk_pattern +Add a drive path pattern to one of the safety lists or make those lists empty. +There are three lists defined which get tested in the following sequence: +.br +If a drive address path matches the "harmless" list then the drive will be +accepted. If it is not a MMC device then the prefix "stdio:" will be prepended +automatically. This list is empty by default. +.br +Else if the path matches the "banned" list then the drive will not be +accepted by xorriso but rather lead to a FAILURE event. This list is empty by +default. +.br +Else if the path matches the "risky" list and if it is not a MMC device, +then its address must have the prefix "stdio:" or it will be rejected. +This list has by default one entry: "/dev". +.br +If a drive path matches no list then it is considered "harmless". By default +these are all paths which do not begin with directory "/dev". +.br +A path matches a list if one of its parent paths or itself matches a list +entry. An eventual address prefix "stdio:" or "mmc:" will be ignored when +testing for matches. +.br +By pseudo-class "clear_list" and pseudo-patterns "banned", "risky", "harmless", +or "all", the lists may be made empty. +.br +E.g.: -drive_class clear_list banned +.br +One will normally define the -drive_class lists in one of the xorriso +Startup Files. +.br +Note: This is not a security feature but rather a bumper for the superuser to +prevent inadverted mishaps. For reliably blocking access to a device file you +have to deny its rw-permissions in the filesystem. +.TP +\fB\-grow_blindly\fR "off"|predicted_nwa +If predicted_nwa is a non-negative number then perform blind growing rather +than modifying if -indev and -outdev are set to different drives. +"off" or "-1" switch to modifying, which is the default. +.br +predicted_nwa is the block address where the add-on session of blind +growing will finally end up. It is the responsibility of the user to ensure +this final position and the presence of the older sessions. Else the +overall ISO image will not be mountable or will produce read errors when +accessing file content. xorriso will write the session to the address +as obtained from examining -outdev and not necessarily to predicted_nwa. +.br +During a run of blind growing, the input drive gets released before output +begins. The output drive gets released when writing is done. +.TP +\fB\-load\fR entity id +Load a particular (possibly outdated) ISO image from a -dev or -indev which +hosts more than one session. Usually all available sessions are shown with +option -toc. +.br +entity depicts the kind of addressing. id depicts the particular +address. The following entities are defined: +.br +"auto" with any id addresses the last session in -toc. This is the default. +.br +"session" with id being a number as of a line "ISO session", column "Idx". +.br +"track" with id being a number as of a line "ISO track", column "Idx". +.br +"lba" or "sbsector" with a number as of a line "ISO ...", column "sbsector". +.br +"volid" with a search pattern for a text as of a line "ISO ...", +column "Volume Id". +.br +Adressing a non-existing entity or one which does not represent an ISO +image will either abandon -indev or at least lead to a blank image. +.br +If an input drive is set at the moment when -load is executed, then the +addressed ISO image is loaded immediately. Else, the setting will be pending +until the next -dev or -indev. After the image has been loaded once, the +setting is valid for -rollback until next -dev or -indev, where it +will be reset to "auto". +.TP +\fB\-assert_volid\fR pattern severity +Refuse to load ISO images with volume ids which do not match the given +search pattern. When refusing an image, give up the input drive and issue +an event of the given severity. An empty search pattern accepts any image. +.br +This option does not hamper the creation of an empty image from blank +input media and does not discard an already loaded image. +.TP +\fB\-in_charset\fR character_set_name +Set the character set from which to convert file names when loading an +image. This has eventually to be done before specifying -dev , -indev or +-rollback. See paragraph "Character sets" for more explanations. +When loading the written image after -commit the setting of -out_charset +will be copied to -in_charset. +.TP +\fB\-rom_toc_scan\fR "on"|"off"[:"emul_on"|"emul_off"] +Read-only drives do not tell the actual media type but show any media as +ROM (e.g. as DVD-ROM). The session history of MMC multi-session media might +be truncated to first and last session or even be completely false. +(The eventual emulated history of overwriteable media is not affected by this.) +.br +To have in case of failure a chance of getting the session history and +especially the address of the last session, there is a scan for ISO 9660 +filesystem headers which might help but also might yield worse results +than the drive's table of content. At its end it can cause read attempts +to invalid addresses and thus ugly drive behavior. +Setting "on" enables that scan for alleged read-only media. +.br +On the other hand the emulation of session history on overwriteable media +can hamper reading of partly damaged media. Setting "off:emul_off" disables +the elsewise trustworthy table-of-content scan for those media. +.br +To be in effect, the -rom_toc_scan setting has to be made before the -*dev +command which aquires drive and media. +.TP +\fB\-ban_stdio_write\fR +Allow for writing only the usage of MMC optical drives. Disallow +to write the result into files of nearly arbitrary type. +Once set, this command cannot be revoked. +.TP +.B Data manipulations: +.PP +The following commands expect file addresses of two kinds: +.br +.B disk_path +is a path to an object in the local filesystem tree. +.br +.B iso_rr_path +is the Rock Ridge name of a file object in the ISO image. (Do not +confuse with the lowlevel ISO 9660 names visible if Rock Ridge gets ignored.) +.PP +Note that in the ISO image you are as powerful as the superuser. Access +permissions of the existing files in the image do not apply to your write +operations. They are intended to be in effect with the read-only mounted image. +.PP +If the iso_rr_path of a newly inserted file leads to an existing +file object in the ISO image, then the following collision handling +happens: +.br +If both objects are directories then they get merged by recursively inserting +the subobjects from filesystem into ISO image. +If other file types collide then the setting of command +.B \-overwrite +decides. +.br +Renaming of files has similar collision handling, but directories can only +be replaced, not merged. Note that -mv inserts the source objects into an +eventual existing target directory rather than attempting to replace it. +.PP +The commands in this section alter the ISO image and not the local filesystem. +.TP +\fB\-iso_rr_pattern\fR "on"|"ls"|"off" +Set the pattern expansion mode for the iso_rr_path arguments of several +commands which support this feature. +.br +.B Pattern expansion +converts a list of pattern words into a list of existing file addresses. +Eventual unmatched pattern words appear themselves in that result list, though. +.br +Pattern matching supports the usual shell parser wildcards '*' '?' '[xyz]' +and respects '/' as separator which may only be matched literally. +.br +Setting "off" disables this feature for all commands which are marked in this +man page by "iso_rr_path [***]" or "iso_rr_pattern [***]". +.br +Setting "on" enables it for all those commands. +.br +Setting "ls" enables it only for those which are marked by +"iso_rr_pattern [***]". +.br +Default is "on". +.TP +\fB\-disk_pattern\fR "on"|"ls"|"off" +Set the pattern expansion mode for the disk_path arguments of several +commands which support this feature. +.br +Setting "off" disables this feature for all commands which are marked in this +man page by "disk_path [***]" or "disk_pattern [***]". +.br +Setting "on" enables it for all those commands. +.br +Setting "ls" enables it only for those which are marked by +"disk_pattern [***]". +.br +Default is "ls". +.TP +\fB\-add\fR pathspec [...] | disk_path [***] +Insert the given files or directory trees from filesystem +into the ISO image. +.br +If -pathspecs is set to "on" then pattern expansion is always disabled and +character '=' has a special meaning. It eventually separates the ISO image path +from the disk path: +.br +iso_rr_path=disk_path +.br +The separator '=' can be escaped by '\\'. +If iso_rr_path does not begin with '/' then -cd is prepended. +If disk_path does not begin with '/' then -cdx is prepended. +.br +If no '=' is given then the word is used as both, iso_rr_path and disk path. +If in this case the word does not begin with '/' then -cdx is prepended to +the disk_path and -cd is prepended to the iso_rr_path. +.br +If -pathspecs is set to "off" then eventual -disk_pattern expansion applies. +The resulting words are used as both, iso_rr_path and disk path. Eventually +-cdx gets prepended to disk_path and -cd to iso_rr_path. +.TP +\fB\-add_plainly\fR mode +If set to mode "unknown" then any command word that does not begin with "-" and +is not recognized as known command will be subject to a virtual -add command. +I.e. it will be used as pathspec or as disk_path and added to the image. +Eventually -disk_pattern expansion applies to disk_paths. +.br +Mode "dashed" is similar to "unknown" but also adds unrecognized command +words even if they begin with "-". +.br +Mode "any" announces that all further words are to be added as pathspecs +or disk_paths. This does not work in dialog mode. +.br +Mode "none" is the default. It prevents any words from being understood +as files to add, if they are not parameters to appropriate commands. +.TP +\fB\-path_list\fR disk_path +Like -add but read the parameter words from file disk_path +or standard input if disk_path is "-". +The list must contain exactly one pathspec resp. disk_path pattern per line. +.TP +\fB\-quoted_path_list\fR disk_path +Like -path_list but with quoted input reading rules. Lines get split into +parameter words for -add. Whitespace outside quotes is discarded. +.TP +\fB\-map\fR disk_path iso_rr_path +Insert file object disk_path into the ISO image as iso_rr_path. If disk_path +is a directory then its whole sub tree is inserted into the ISO image. +.TP +\fB\-map_single\fR disk_path iso_rr_path +Like -map, but if disk_path is a directory then its sub tree is not inserted. +.TP +\fB\-map_l\fR disk_prefix iso_rr_prefix disk_path [***] +Perform -map with each of the disk_path arguments. iso_rr_path will be +composed from disk_path by replacing disk_prefix by iso_rr_prefix. +.TP +\fB\-update\fR disk_path iso_rr_path +Compare file object disk_path with file object iso_rr_path. If they do not +match, then perform the necessary image manipulations to make iso_rr_path +a matching copy of disk_path. This comparison will imply lengthy content +reading before a decision is made. On the other hand it strives for the +smallest possible amount of add-on data which is needed to achieve the +matching copy. +.br +If disk_path is a directory and iso_rr_path does not exist yet, then the +whole subtree will be inserted. Else only directory attributes will be +updated. +.TP +\fB\-update_r\fR disk_path iso_rr_path +Like -update but working recursively. I.e. all file objects below both +addresses get compared whether they have counterparts below the other address +and whether both counterparts match. If there is a mismatch then the necessary +update manipulation is done. +.br +Note that the comparison result may depend on option -follow. Its setting +should always be the same as with the first adding of disk_path as iso_rr_path. +.br +If iso_rr_path does not exist yet, then it gets added. If disk_path does not +exist, then iso_rr_path gets deleted. +.TP +\fB\-update_l\fR disk_prefix iso_rr_prefix disk_path [***] +Perform -update_r with each of the disk_path arguments. iso_rr_path will be +composed from disk_path by replacing disk_prefix by iso_rr_prefix. +.TP +\fB\-cut_out\fR disk_path byte_offset byte_count iso_rr_path +Map a byte interval of a regular disk file into a regular file in the ISO +image. +This may be necessary if the disk file is larger than a single media, or if +it exceeds the traditional limit of 2 GiB - 1 for old operating systems, +or the limit of 4 GiB - 1 for newer ones. Only the newest Linux kernels +seem to read properly files >= 4 GiB - 1. +.br +A clumsy remedy for this limit is to backup file pieces and to concatenate +them at restore time. A well tested chopping size is 2047m. +It is permissible to request a higher byte_count than available. The +resulting file will be truncated to the correct size of a final piece. +To request a byte_offset higher than available yields no file in +the ISO image but a SORRY event. +E.g: +.br + -cut_out /my/disk/file 0 2047m \\ +.br + /file/part_1_of_3_at_0_with_2047m_of_5753194821 \\ +.br + -cut_out /my/disk/file 2047m 2047m \\ +.br + /file/part_2_of_3_at_2047m_with_2047m_of_5753194821 \\ +.br + -cut_out /my/disk/file 4094m 2047m \\ +.br + /file/part_3_of_3_at_4094m_with_2047m_of_5753194821 +.br +-cut_out is coordinated with -compare* and -update* if the names of the +part files follow a convention by which xorriso is able to recognize +file parts and process them accordingly: +.br +A disk file gets mapped to an ISO directory containing its split parts +as regular files. The parts have names which describe the splitting +by 5 numbers which are separated by some non-numerical text: +.br +part_number, total_parts, byte_offset, byte_count, disk_file_size +.br +Scaling characters like "m" or "k" are taken into respect and may +serve as separators as well. All digits are interpreted as decimal, +even if leading zeros are present. +.br +Not all parts have to be present on the same media. But those parts +which are present have to sit in the same directory. No other files +are allowed in there. Parts have to be disjoint. Their numbers have +to be plausible. E.g. byte_count must be valid as -cut_out argument +and it must be the same with all parts. +.br +If the disk file grows enough to need new parts then those get added +to the directory if it already contains all parts of the old disk file. +If not all parts are present, then only those present parts will +be updated. +.TP +\fB\-cpr\fR disk_path [***] iso_rr_path +Insert the given files or directory trees from filesystem +into the ISO image. +.br +The rules for generating the ISO addresses are similar as with +shell command cp -r. Nevertheless, directories of the iso_rr_path +are created if necessary. Especially a not yet existing iso_rr_path +will be handled as directory if multiple disk_paths are present. +The leafnames of the multiple disk_paths will be grafted under that +directory as would be done with an existing directory. +.br +If a single disk_path is present then a non-existing iso_rr_path will +get the same type as the disk_path. +.br +If a disk_path does not begin with '/' then -cdx is prepended. +If the iso_rr_path does not begin with '/' then -cd is prepended. +.TP +\fB\-rm\fR iso_rr_path [***] +Delete the given files from the ISO image. +.br +Note: This does not free any space on the -indev media, even if +the deletion is committed to that same media. +.br +The image size will shrink if the image is written to a different +media in modification mode. +.TP +\fB\-rm_r\fR iso_rr_path [***] +Delete the given files or directory trees from the ISO image. +See also the note with option -rm. +.TP +\fB\-mv\fR iso_rr_path [***] iso_rr_path +Rename the given file objects in the ISO tree to the last +argument in the list. Use the same rules as with shell command mv. +.br +If pattern expansion is enabled and if the last argument contains wildcard +characters then it must match exactly one existing file address, or else the +command fails with a FAILURE event. +.TP +\fB\-chown\fR uid iso_rr_path [***] +Set ownership of file objects in the ISO image. uid may either be a decimal +number or the name of a user known to the operating system. +.TP +\fB\-chown_r\fR uid iso_rr_path [***] +Like -chown but affecting all files below eventual directories. +.TP +\fB\-chgrp\fR gid iso_rr_path [***] +Set group attribute of file objects in the ISO image. gid may either be a +decimal number or the name of a group known to the operating system. +.TP +\fB\-chgrp_r\fR gid iso_rr_path [***] +Like -chgrp but affecting all files below eventual directories. +.TP +\fB\-chmod\fR mode iso_rr_path [***] +Equivalent to shell command chmod in the ISO image. +mode is either an octal number beginning with "0" or a comma separated +list of statements of the form [ugoa]*[+-=][rwxst]* . +.br +Like: go-rwx,u+rwx . +.br +.B Personalities: +u=user, g=group, o=others, a=all +.br +.B Operators: ++ adds given permissions, - revokes given permissions, += revokes all old permissions and then adds the given ones. +.br +.B Permissions: +r=read, w=write, x=execute|inspect, s=setuid|setgid, t=sticky bit +.br +For octal numbers see man 2 stat. +.TP +\fB\-chmod_r\fR mode iso_rr_path [***] +Like -chmod but affecting all files below eventual directories. +.TP +\fB\-alter_date\fR type timestring iso_rr_path [***] +Alter the date entries of a file in the ISO image. type is +one of "a", "m", "b" for access time, modification time, +both times. +.br +timestring may be in the following formats +(see also section EXAMPLES): +.br +As expected by program date: + MMDDhhmm[[CC]YY][.ss]] +.br +As produced by program date: + [Day] MMM DD hh:mm:ss [TZON] YYYY +.br +Relative times counted from current clock time: + +|-Number["s"|"h"|"d"|"w"|"m"|"y"] +.br +where "s" means seconds, "h" hours, "d" days, "w" weeks, "m"=30d, +"y"=365.25d plus 1d added to multiplication result. +.br +Absolute seconds counted from Jan 1 1970: + =Number +.br +xorriso's own timestamps: + YYYY.MM.DD[.hh[mm[ss]]] +.br +scdbackup timestamps: + YYMMDD[.hhmm[ss]] +.br +where "A0" is year 2000, "B0" is 2010, etc. +.TP +\fB\-alter_date_r\fR type timestring iso_rr_path [***] +Like -alter_date but affecting all files below eventual directories. +.TP +\fB\-find\fR iso_rr_path [test [test ...]] [-exec action [params]] -- +A very restricted substitute for shell command find in the ISO image. +It performs an action on matching file objects at or below iso_rr_path. +.br +Tests are optional. If they are omitted then action is applied to all file +objects. If tests are given then action is applied only if all of them +match the file object. Available tests are: +.br +-name pattern +.br +Pattern is not expanded but used for comparison with +the particular file names of the eventual directory tree underneath +iso_rr_path. +.br +-type type_letter +.br +matches only files files of the given type: +"block", "char", "dir", "pipe", "file", "link", "socket", "eltorito", +"Xotic" which eventually matches what is not matched by the other types. +.br +Only the first letter is interpreted. E.g.: -find / -type d +.br +-damaged +.br +matches only files which use data blocks marked as damaged by a previous +run of -check_media. The damage info vanishes when a new ISO image gets +loaded. +.br +-undamaged +.br +matches only files which use data blocks outside the areas marked as damaged. +.br +-lba_range start_lba block_count +.br +matches only files which use data blocks within the range of start_lba +and start_lba+block_count-1. +.br +Default action is "echo", +i.e. to print the address of the found file. Other actions are certain +xorriso commands which get performed on the found files. These commands +may have specific parameters. See also their particular descriptions. +.br +"chown" and "chown_r" change the ownership and get the user id as param. E.g.: +.br + -find / -exec chown thomas -- +.br +"chgrp" and "chgrp_r" change the group attribute and get the group id as param. +E.g.: +.br + -find / name 'news*' -type d -exec chgrp_r staff -- +.br +"chmod" and "chmod_r" change access permissions and get a mode string as param. +E.g.: +.br + -find / -exec chmod a-w,a+r -- +.br +"alter_date" and "alter_date_r" change the timestamps. +They get a type character and a timestring as params. +E.g.: +.br + -find / -exec alter_date "m" "Dec 30 19:34:12 2007" -- +.br +"lsdl" prints file information like shell command ls -dl. +E.g.: +.br + -find / -exec lsdl -- +.br +"compare" performs command -compare with the found file address as iso_rr_path +and the corresponding file address below its argument disk_path_start. For this +the iso_rr_path of the -find command gets replaced by the disk_path_start. +E.g.: +.br + -find / -exec compare /home/thomas -- +.br +"update" performs command -update with the found file address as iso_rr_path. +The corresponding file address is determined like with above "compare". +.br +E.g.: +.br + -find / -exec update /home/thomas -- +.br +"rm" removes the found iso_rr_path from the image if it is not a directory with +files in it. I.e. this "rm" includes "rmdir". +.br +E.g.: +.br + -find / -name *.doc -exec rm -- +.br +"rm_r" removes the found iso_rr_path from the image, including whole directory +trees. +.br +E.g.: +.br + -find /uh/oh -name *private* -exec rm_r -- +.br +"report_damage" classifies files whether they hit a data block that is +marked as damaged. The result is printed together with the eventual address +of the first damaged byte, the maximum span of damages, file size, and the +path of the file. +.br +E.g.: +.br + -find / -damaged -exec report_damage +.br +"report_lba" prints files which are associated to image data blocks. +It tells the logical block address, the block number, the byte size, +and the path of each file. There may be reported more than one +line per file if the file is very large. In this case each line has a +different extent number in column "xt". +.br +E.g.: +.br + -find / -lba_range 302000 50000 -exec report_lba +.br +"find" performs another run of -find on the matching file address. It accepts +the same params as -find, except iso_rr_path. +E.g.: +.br + -find / -name '???' -type d -exec find -name '[abc]*' -exec chmod a-w,a+r -- +.br +If not used as last command in the line then the argument list +needs to get terminated by "--". +.TP +\fB\-mkdir\fR iso_rr_path [...] +Create empty directories if they do not exist yet. +Existence as directory generates a WARNING event, existence as +other file causes a FAILURE event. +.TP +\fB\-rmdir\fR iso_rr_path [***] +Delete empty directories. +.TP +\fB\-rollback\fR +Discard the manipulated ISO image and reload it from -indev. +.TP +\fB\-rollback_end\fR +Discard the manipulated ISO image.

It is not unnormal with several +types of media that there is no progress visible for the first +few minutes or that the drive gnaws on the media for a few +minutes after all data have been transmitted. +xorriso and the drives are in a client-server relationship. +The drives have much freedom about what to do with the media. +Some combinations of drives and media simply do not work, +despite the promises by their vendors. +If writing fails - or even the drive gets stuck and you need +to reboot - then try other media or another drive. The reason +for such failure is hardly ever in the code of the various +burn programs but you may well try some of those listed below +under SEE ALSO. +.TP +\fB\-eject\fR "in"|"out"|"all" +Eject the media in -indev, resp. -outdev, resp. both drives. +Note: It is not possible yet to effectively eject disk files. +.TP +\fB\-commit_eject\fR "in"|"out"|"all"|"none" +Combined -commit and -eject.

Eventually give up any non-ejected drive. +.TP +\fB\-blank\fR mode +Make media ready for writing from scratch (if not -dummy is activated). +.br +This affects only the -outdev not the -indev. +If both drives are the same and if the ISO image was altered +then this command leads to a FAILURE event. +Defined modes are: + as_needed, fast, all, deformat, deformat_quickest +.br +"as_needed" cares for used CD-RW, DVD-RW and for used overwriteable media +by applying -blank "fast". It applies -format "full" to yet unformatted +DVD-RAM and BD-RE. Other media in blank state are gracefully ignored. +Media which cannot be made ready for writing from scratch cause a FAILURE +event. +.br +"fast" and "all" make CD-RW and unformatted DVD-RW re-usable, +or invalidate overwriteable ISO images. +.br +"deformat" converts overwriteable DVD-RW into unformatted ones. +.br +"deformat_quickest" is a faster way to deformat or blank DVD-RW +but produces media which are only suitable for a single session. +xorriso will write onto them only if option -close is set to "on". +.br +The progress reports issued by some drives while blanking are +quite unrealistic. Do not conclude success or failure from the +reported percentages. Blanking was successful if no SORRY event or +worse occured. +.TP +\fB\-format\fR mode +Convert unformatted DVD-RW into overwriteable ones, "de-ice" DVD+RW, format +newly purchased BD-RE or BD-R, re-format DVD-RAM or BD-RE. +.br +Defined modes are: +.br + as_needed, full, fast, by_index_<num>, fast_by_index_<num> +.br +"as_needed" formats yet unformatted DVD-RW, DVD-RAM, BD-RE, or blank +unformatted BD-R. Other media are left untouched. +.br +"full" (re-)formats DVD-RW, DVD+RW, DVD-RAM, BD-RE, or blank unformatted BD-R. +.br +"fast" does the same as "full" but tries to be quicker. +.br +"by_index_" selects a format out of the descriptor list issued by option +-list_formats. The index number from that list is to be appended to the +mode word. E.g: "by_index_3". +.br +"fast_by_index_" does the same as "by_index_" but tries to be quicker. +.br +"by_size_" selects a format out of the descriptor list which provides at +least the given size. That size is to be appended to the mode word. +E.g: "by_size_4100m". This applies to media with Defect Management. +.br +"fast_by_size_" does the same as "by_size_" but tries to be quicker. +.br +The formatting action has no effect on media if -dummy is activated. +.br +Formatting is normally needed only once during the lifetime of a media, +if ever. But it is a reason for re-formatting if: +.br + DVD-RW was deformatted by -blank, +.br + DVD+RW has read failures (re-format before next write), +.br + DVD-RAM or BD-RE shall change their amount of defect reserve. +.br +BD-R may be written unformatted or may be formatted before first use. +Formatting activates Defect Management which tries to catch and repair +bad spots on media during the write process at the expense of half speed +even with flawless media. +.br +The progress reports issued by some drives while formatting are +quite unrealistic. Do not conclude success or failure from the +reported percentages. Formatting was successful if no SORRY event +or worse occured.

The list gives the index number after "Format idx", +a MMC format code, the announced size in blocks (like "2236704s") +and the same size in MiB. +.br +MMC format codes are manifold. Most important are: +"00h" general formatting, "01h" increases reserve space for DVD-RAM, +"26h" for DVD+RW, "30h" for BD-RE with reserve space, +"31h" for BD-RE without reserve space, "32h" for BD-R. +.br +Smaller format size with DVD-RAM, BD-RE, or BD-R means more reserve space. +.TP +.B Settings for data insertion: +.TP +\fB\-file_size_limit\fR value [value [...]] -- +Set the maximum permissible size for a single data file. The values get +summed up for the actual limit. If the only value is "off" then the file +size is not limited by xorriso. Default is a limit of 100 extents, 4g -2k each: +.br + -file_size_limit 400g -200k -- +.br +When mounting ISO 9660 filesystems, old operating systems can handle only files +up to 2g -1 --. Newer ones are good up to 4g -1 --. +You need quite a new Linux kernel to read correctly the final bytes +of a file >= 4g if its size is not aligned to 2048 byte blocks. +.br +xorriso's own data read capabilities are not affected by eventual +operating system size limits. They apply to mounting only. Nevertheless, +the target filesystem of an -extract must be able to take the file size. +.TP +\fB\-not_mgt\fR code[:code[...]] +Control the behavior of the exclusion lists. +.br +Exclusion processing happens before disk_paths get mapped to the ISO image +and before disk files get compared with image files. +The absolute disk path of the source is matched against the -not_paths list. +The leafname of the disk path is matched against the patterns in the -not_leaf +list. If a match is detected then the disk path will not be regarded as an +existing file and not be added to the ISO image. +.br +Several codes are defined. +The _on/_off settings persist until they are revoked by their_off/_on +counterparts. +.br +"erase" empties the lists which were accumulated by -not_paths and -not_leaf. +.br +"reset" is like "erase" but also re-installs default behavior. +.br +"off" disables exclusion processing temporarily without invalidating +the lists and settings. +.br +"on" re-enables exclusion processing. +.br +"param_off" applies exclusion processing only to paths below disk_path +parameter of commands. I.e. explicitely given disk_paths are exempted +from exclusion processing. +.br +"param_on" applies exclusion processing to command parameters as well as +to files below such parameters. +.br +"subtree_off" with "param_on" excludes parameter paths only if they +match a -not_paths item exactly. +.br +"subtree_on" additionally excludes parameter paths which lead to a file +address below any -not_paths item. +.br +"ignore_off" treats excluded disk files as if they were missing. I.e. they +get reported with -compare and deleted from the image with -update. +.br +"ignore_on" keeps excluded files out of -compare or -update activities. +.TP +\fB\-not_paths\fR disk_path [***] +Add the given paths to the list of excluded absolute disk paths. If a given +path is relative, then the current -cdx is prepended to form an absolute path. +Eventual pattern matching happens at definition time and not when exclusion +checks are made. +.br +(Do not forget to end the list of disk_paths by "--") +.TP +\fB\-not_leaf\fR pattern +Add a single shell parser style pattern to the list of exclusions for +disk leafnames. These patterns are evaluated when the exclusion checks are +made. +.TP +\fB\-not_list\fR disk_path +Read lines from disk_path and use each of them either as -not_paths argument, +if they contain a / character, or as -not_leaf pattern. +.TP +\fB\-quoted_not_list\fR disk_path +Like -not_list but with quoted input reading rules. Each word is +handled as one argument for -not_paths resp. -not_leaf. +.TP +\fB\-follow\fR occasion[:occasion[...]] +Enable or disable resolution of symbolic links and mountpoints under +disk_paths. This applies to actions -add, -du*x, -ls*x, -findx, +and to -disk_pattern expansion. +.br +There are two kinds of follow decisison to be made: +.br +"link" is the hop from a symbolic link to its target file object. +If enabled then symbolic links are handled as their target file objects, +else symbolic links are handled as themselves. +.br +"mount" is the hop from one filesystem to another subordinate filesystem. +If enabled then mountpoint directories are handled as any other directory, +else mountpoints are handled as empty directories if they are encountered in +directory tree traversals. +.br +Less general than above occasions: +.br +"pattern" is mount and link hopping, but only during -disk_pattern expansion. +.br +"param" is link hopping for parameter words (after eventual pattern expansion). +If enabled then -ls*x will show the link targets rather than the links +themselves. -du*x, -findx, and -add will process the link targets but not +follow links in an eventual directory tree below the targets (unless "link" +is enabled). +.br +Occasions can be combined in a colon separated list. All occasions +mentioned in the list will then lead to a positive follow decision. +.br +"off" prevents any positive follow decision. Use it if no other occasion +applies. +.br +Shortcuts: +.br +"default" is equivalent to "pattern:mount:limit=100". +.br +"on" always decides positive. Equivalent to "link:mount". +.br + +Not an occasion but an optional setting is: +.br +"limit="<number> which sets the maximum number of link hops. +A link hop consists of a sequence of symbolic links and a final target +of different type. Nevertheless those hops can loop. Example: +.br + \fB$\fR ln -s .. uploop +.br +Link hopping has a builtin loop detection which stops hopping at the first +repetition of a link target. Then the repeated link is handled as itself +and not as its target. +Regrettably one can construct link networks which +cause exponential workload before their loops get detected. +The number given with "limit=" can curb this workload at the risk of truncating +an intentional sequence of link hops. +.TP +\fB\-pathspecs\fR "on"|"off" +Control parameter interpretation with xorriso actions -add and -path_list. +.br +"on" enables pathspecs of the form +.B target=source +like with program mkisofs -graft-points. +It also disables -disk_pattern expansion for command -add. +.br +"off" disables pathspecs of the form target=source +and eventually enables -disk_pattern expansion. +.TP +\fB\-overwrite\fR "on"|"nondir"|"off" +Allow or disallow to overwrite existing files in the +ISO image by files with the same user defined name. +.br +With setting "off", name collisions cause FAILURE events. +With setting "nondir", only directories are protected by such events, other +existing file types get treated with -rm before the new file gets added. +Setting "on" allows automatic -rm_r. I.e. a non-directory can replace an +existing directory and all its subordinates. +.br +If restoring of files is enabled, then the overwrite rule applies to the +target file objects on disk as well, but "on" is downgraded to "nondir". +.TP +\fB\-split_size\fR number["k"|"m"] +Set the threshold for automatic splitting of regular files. Such splitting +maps a large disk file onto a ISO directory with several part files in it. +This is necessary if the size of the disk file exceeds -file_size_limit. +Older operating systems can handle files in mounted ISO 9660 filesystems +only if they are smaller than 2 GiB resp. 4 GiB. +See also option -cut_out for more information about file parts. +.br +Default is 0 which will exclude files larger than -file_size_limit by a +FAILURE event. +A well tested -split_size is 2047m. Sizes above -file_size_limit are not +permissible. +.TP +.B Settings for result writing: +.TP +Rock Ridge info will be generated by the program unconditionally. +.TP +\fB\-joliet\fR "on"|"off" +If enabled by "on", generate Joliet info additional to Rock Ridge info. +.TP +\fB\-compliance\fR rule[:rule...] +Adjust the compliance to specifications of ISO 9660 and its extensions. In some +cases it is worth to deviate a bit in order to circumvent bugs of the intended +reader system or to get inofficial extra features. +.br +There are several adjustable rules which have a keyword each. If they +are mentioned with this option then their rule gets added to the relaxation +list. This list can be erased by rules "strict" or "clear". It can be reset +to its start setting by "default". All of the following relaxation rules +can be revoked individually by appending "_off". Like "deep_paths_off". +.br +Rule keywords are: +.br +"omit_version" do not add versions (";1") to the file names. +.br +"deep_paths" allow ISO file paths deeper than 8 levels. +.br +"long_paths" allow ISO file paths longer than 255 characters. +.br +"long_names" allow up to 37 characters with ISO file names. +.br +"no_force_dots" do not add a dot to filenames which have none. +.br +"lowercase" allow lowercase characters in ISO file names. +.br +"full_ascii" allow all ASCII characters in ISO file names. +.br +"joliet_long_paths" allow Joliet paths longer than 240 characters. +.br +"always_gmt" store timestamps in GMT representation with timezone 0. +.br +"old_rr" use Rock Ridge version 1.10 (needed if the intended reader +system does not recognize Rock Ridge 1.12 signature). +.br +"rec_mtime" record with ISO files the disk file's mtime and not the +creation time of the image. +.br +Default setting is "clear:deep_paths:long_paths:always_gmt". +.br +Note: The term "ISO file" means the plain ISO 9660 names wnd attributes +which get visible if the reader ignores Rock Ridge. +.TP +\fB\-volid\fR text +Specify the volume ID. xorriso accepts any text up to 32 characters, +but according to rarely obeyed specs stricter rules apply: +.br +ECMA 119 demands ASCII characters out of [A-Z0-9_]. Like: "IMAGE_23" +.br +Joliet allows 16 UCS-2 characters. Like: "Windows name" +.br +Be aware that the volume id might get used automatically as name of the +mount point when the media is inserted into a playful computer system. +.br +If an ISO image gets loaded while the volume ID is set to default "ISOIMAGE" +or to "", then the volume ID of the loaded image will become the effective +volume id for the next write run. But as soon as command -volid is performed +afterwards, this pending id is overridden by the new setting. +.br +Consider this when setting -volid "ISOIMAGE" before executing -dev, -indev, +or -rollback. +If you insist in -volid "ISOIMAGE", set it again after those commands. +.TP +\fB\-publisher\fR text +Set the publisher string to be written with the next -commit. Permissible +are up to 128 characters. +.TP +\fB\-application_id\fR text +Set the application id string to be written with the next -commit. Permissible +are up to 128 characters. +.TP +\fB\-out_charset\fR character_set_name +Set the character set to which file names get converted when writing an +image. See paragraph "Character sets" for more explanations. +When loading the written image after -commit the setting of -out_charset +will be copied to -in_charset. +.TP +\fB\-uid\fR uid +User id to be used for all files when the new ISO tree gets written to media. +.TP +\fB\-gid\fR gid +Group id to be used for all files when the new ISO tree gets written to media. +.TP +\fB\-speed\fR number[k|m|c|d|b] +Set the burn speed. Default is 0 = maximum speed. +Speed can be given in media dependent numbers or as a +desired throughput per second in MMC compliant kB (= 1000) +or MB (= 1000 kB). Media x-speed factor can be set explicity +by "c" for CD, "d" for DVD, "b" for BD, "x" is optional. +.br +Example speeds: +.br + 706k = 706kB/s = 4c = 4xCD +.br + 5540k = 5540kB/s = 4d = 4xDVD +.br +If there is no hint about the speed unit attached, then the +media in the -outdev will decide. Default unit is CD = 176.4k. +.br +MMC drives usually activate their own idea of speed and take +the speed value given by the burn program only as upper limit +for their own decision. +.TP +\fB\-stream_recording\fR "on"|"off" +Setting "on" tries to circumvent the management of defects on DVD-RAM, BD-RE, +or BD-R. Defect management keeps partly damaged media usable. But it reduces +write speed to half nominal speed even if the media is in perfect shape. +For the case of flawless media, one may use -stream_recording "on" to get +full speed. +.TP +\fB\-dummy\fR "on"|"off" +If "on" then simulate burning or refuse with FAILURE event if +no simulation is possible, do neither blank nor format. +.TP +\fB-fs\fR number["k"|"m"] +Set the size of the fifo buffer which smoothens the data +stream from ISO image generation to media burning. Default +is 4 MiB, minimum 64 kiB, maximum 1 GiB. +The number may be followed by letter "k" or "m" +which means unit is kiB (= 1024) or MiB (= 1024 kiB). +.TP +\fB\-close\fR "on"|"off" +If "on" then mark the written media as not appendable +any more (if possible at all with the given type of target media). +.br +This is the contrary of cdrecord, wodim, cdrskin option -multi, +and is one aspect of growisofs option -dvd-compat. +.TP +\fB\-padding\fR number["k"|"m"] +Append the given number of extra bytes to the image stream. +This is a traditional remedy for a traditional bug in block +device read drivers. Needed only for CD recordings in TAO mode. +Since one can hardly predict on what media an image might end up, +xorriso adds the traditional 300k of padding by default to all images. +.br +For images which will never get to a CD it is safe to use -padding 0 . +.TP +.B El Torito bootable ISO images: +.PP +Contrary to published specifications many BIOSes will load an El Torito +object from the first session on media and not from the last one, which +gets mounted by default. This makes no problems with overwriteable media, +because they appear to inadverted readers as one single session. +.br +But with multi-session media CD-R[W], DVD-R[W], DVD+R, it implies that the +whole bootable system has to reside already in the first session and that +the last session still has to bear all files which the booted system expects +after eventually mounting the ISO image. +.br +If ISOLINUX is known to be present on media then it is advised to patch it +when a follow-up session gets written. But one should not rely on the +capability to influence the bootability of the existing sessions, unless one +can assume overwriteable media. +.TP +\fB\-boot_image\fR "any"|"isolinux" +.br + "discard"|"keep"|"patch"|"show_status"|bootspec +.br +Define the handling of an eventual El Torito object which has +been read from an existing ISO image or defines how to make a prepared +ISOLINUX file set bootable. +.br + +All types ("any") of El Torito boot images can be discarded or kept unaltered. +The latter makes only sense if the format of the boot image is +relocatable without content changes. +.br +With any type, "show_status" will print what is known about the loaded image +and its designated fate. +.br +An existing boot image of type "isolinux" can be discarded or it can be +patched to match its relocation. In the latter case the resulting ISO image +stays bootable if the boot image was really produced by ISOLINUX. +.br +CAUTION: +This is an expert option. +xorriso cannot recognize the inner form of boot images. +So the user has already to know about the particular needs of the +boot image which is present on the input media. +.br +Most safe is the default: -boot_image "any" "discard". +.br + +A bootspec is a word of the form name=value and is used to describe the +activation of a ISOLINUX boot image by an El Torito record and eventually +a MBR. The names "dir" and "bin_path" lead to boot image activation. +.br +On all media types this is possible within the first session. In further +sessions an existing boot image can get replaced by a new one, but depending +on the media type this may have few effect at boot time. See above. +.br +The ISOLINUX files have to be added to the ISO image by normal means +(image loading, -map, -add, ...) and should reside either in ISO image +directory /isolinux or in /boot/isolinux . +In that case it suffices to use as bootspec the text "dir=/isolinux" or +"dir=/boot/isolinux". E.g.: +.br + -boot_image isolinux dir=/boot/isolinux +.br +which bundles these individual settings: +.br + -boot_image isolinux bin_path=/boot/isolinux/isolinux.bin +.br + -boot_image isolinux cat_path=/boot/isolinux/boot.cat +.br + -boot_image isolinux load_size=2048 +.br +bin_path depicts the binary program which is to be started by the BIOS at +boot time. It is among the files produced by ISOLINUX. +.br +An El Torito boot catalog file gets inserted into the ISO image with address +cat_path at -commit time. +It is subject to normal -overwrite and -reassure processing if there is already +a file with the same name. +.br +Bootspec "isohybrid=off" disables MBR generation, "isohybrid=on" prevents the +write session if not the isohybrid signature is found in the bin_path file. +Default is "isohybrid=auto" which silently omits the MBR if the signature is +missing. +.TP +.B Character sets: +.PP +File names are strings of non-zero bytes with 8 bit each. Unfortunately +the same byte string may appear as different peculiar national characters +on differently nationalized computers. +The meanings of byte codes are defined in \fBcharacter sets\fR which have +names. Shell command iconv -l lists them. +.br +Character sets should not matter as long as only english alphanumeric +characters are used for file names or as long as all writers and readers +of the media use the same character set. +Outside these constraints it may be necessary to let xorriso convert byte +codes. +.br +There is an input conversion from input character set to the local character +set which applies when an ISO image gets loaded. A conversion from local +character set to the output character set is performed when an +image tree gets written. The sets can be defined independently by options +-in_charset and -out_charset. Normally one will have both identical, if ever. +.br +If conversions are desired then xorriso needs to know the name of the +local character set. xorriso can inquire the same info as shell command +"locale" with argument "charmap". This may be influenced by environment +variables LC_ALL, LC_CTYPE, or LANG and should match the expectations of +the terminal. +.TP +\fB\-charset\fR character_set_name +Set the character set from which to convert file names when loading an +image and to which to convert when writing an image. +.TP +\fB\-local_charset\fR character_set_name +Override the system assumption of the local character set name. +If this appears necessary, one should consider to set -backslash_codes to +"on" in order to avoid dangerous binary codes being sent to the terminal. +.TP +.B Exception processing: +.PP +Since the tasks of xorriso are manifold and prone to external influence, there +may arise the need for xorriso to report and handle problem events. +.br +Those events get classified when they are detected by one of the software +modules and forwarded to reporting and evaluation modules which decide about +reactions. Event classes are sorted by severity: +.br +"NEVER" The upper end of the severity spectrum. +.br +"ABORT" The program is being aborted and on its way to end. +.br +"FATAL" The main purpose of the run failed +or an important resource failed unexpectedly. +.br +"FAILURE" An important part of the job could not be performed. +.br +"MISHAP" A FAILURE which can be tolerated during ISO image generation. +.br +"SORRY" A less important part of the job could not be performed. +.br +"WARNING" A situation is suspicious of being not intended by the user. +.br +"HINT" A proposal to the user how to achieve better results. +.br +"NOTE" A harmless information about noteworthy circumstances. +.br +"UPDATE" A pacifier message during long running operations. +.br +"DEBUG" A message which would only interest the program developers. +.br +"ALL" The lower end of the severity spectrum. +.TP +\fB\-abort_on\fR severity +Set the severity threshold for events to abort the program. +.br +Useful: "NEVER", "ABORT", "FATAL", "FAILURE" , "MISHAP", "SORRY" +.br +It may become necessary to abort the program anyway, despite +the setting by this option. Expect not many "ABORT" events to +be ignorable. +.br +A special property of this option is that it works preemptive if given as +program start argument. I.e. the first -abort_on setting among the +start arguments is in effect already when the first operations of xorriso +begin. Only "-abort_on" with dash "-" is recognized that way. +.TP +\fB\-return_with\fR severity exit_value +Set the threshold and exit_value to be returned at program end if no abort +has happened. This is to allow xorriso to go on after problems but to get +a failure indicating exit value from the program, nevertheless. +Useful is a value lower than the -abort_on threshold, down to "WARNING". +.br +exit_value may be either 0 (indicating success to the starter of the program) +or a number between 32 and 63. Some other exit_values are used by xorriso if +it decides to abort the program run: +.br +1=abort due to external signal +.br +2=no program arguments given +.br +3=creation of xorriso main object failed +.br +4=failure to start libburnia-project.org libraries +.br +5=program abort during argument processing +.br +6=program abort during dialog processing +.TP +\fB\-report_about\fR severity +Set the threshold for events to be reported. +.br +Useful: "SORRY", "WARNING", "HINT", "NOTE", "UPDATE", "DEBUG", "ALL" +.br +Regardless what is set by -report_about, messages get always reported if they +reach the severity threshold of -abort_on . +.br +Event messages are sent to the info channel "I" which is usually stderr +but may be influenced by command -pkt_output. +Info messages which belong to no event get attributed severity "NOTE". +.br +A special property of this option is that the first -report_about setting +among the start arguments is in effect already when the first operations +of xorriso begin. Only "-report_about" with dash "-" is recognized that way. +.TP +\fB\-error_behavior\fR occasion behavior +Control the program behavior at problem event occasions. +For now this applies to occasions "image_loading" which is given while +an image tree is read from the input device, and to "file_extraction" which +is given with osirrox options like -extract. +.br +With "image_loading" there are three behaviors available: +.br +"best_effort" goes on with reading after events with severity below FAILURE +if the threshold of option -abort_on allows this. +.br +"failure" aborts image tree reading on first event of at least SORRY. +It issues an own FAILURE event. +.br +"fatal" acts like "failure" but issues the own event as FATAL. +This is the default. +.br +With occasion "file_extraction" there are three behaviors: +.br +"keep" maintains incompletely extracted files on disk. This is the default. +.br +"delete" removes files which encountered errors during content extraction. +.br +"best_effort" starts a revovery attempt by means of -extract_cut. +.TP +.B Dialog mode control: +.TP +\fB\-dialog\fR "on"|"off"|"single_line" +Enable or disable to enter dialog mode after all arguments are processed. +In dialog mode input lines get prompted via readline or from stdin. +.br +Mode "on" supports input of newline characters within quotation marks and +line continuation by trailing backslash outside quotation marks. +Mode "single_line" does not. +.TP +\fB\-page\fR length width +Describe terminal to the text pager. See also above, paragraph Result pager. +.br +If parameter length is nonzero then the user gets prompted after that +number of terminal lines. Zero length disables paging. +.br +Parameter width is the number of characters per terminal line. It is used +to compute the number of terminal lines which get occupied by an output line. +A usual terminal width is 80. +.TP +\fB\-use_readline\fR "on"|"off" +If "on" then use readline for dialog. Else use plain stdin. +.br +See also above, paragraph Dialog, Readline, Result pager. +.TP +\fB\-reassure\fR "on"|"tree"|"off" +If "on" then ask the user for "y" or "n": +.br +before deleting or overwriting any file in the ISO image, +.br +before overwriting any disk file during restore operations, +.br +before rolling back pending image changes, +.br +before committing image changes to media, +.br +before changing the input drive, +.br +before blanking or formatting media, +.br +before ending the program. +.br +With setting "tree" the reassuring prompt will appear for an eventual +directory only once and not for each file in its whole subtree. +.br +Setting "off" silently kills any kind of image file object resp. performs +above irrevocable actions. +.br +To really produce user prompts, option -dialog needs to be set to "on". +Note that the prompt does not appear in situations where file removal +is forbidden by option -overwrite. -reassure only imposes an additional +curb for removing existing file objects. +.br +Be aware that file objects get deleted from the ISO image immediately +after confirmation. They are gone even if the running command gets aborted +and its desired effect gets revoked. In case of severe mess-up, consider to +use -rollback to revoke the whole session. +.TP +.B Drive and media related inquiry actions: +.TP +\fB\-devices\fR +Show list of available MMC drives with the addresses of +their libburn standard device files. +.br +This is only possible when no ISO image changes are pending. +After this option was executed, there is no drive current +and no image loaded. Eventually one has to aquire a drive again. +.br +In order to be visible, a device has to offer rw-permissions +with its libburn standard device file. Thus it might be only the +.B superuser +who is able to see all drives. +.br +Drives which are occupied by other processes get not shown. +.TP +\fB\-toc\fR +.br +Show media specific table of content. This is the media session history, +not the ISO image directory tree. +.br +In case of overwriteable media holding a valid ISO image, a single session +gets fabricated from the ISO image size info. But if the first session on the +overwriteable media was written by xorriso then in most cases a complete +session history can be emulated. +.br +A drive which is incapable of writing may show any media as CD-ROM or DVD-ROM +with only one or two sessions on it. The last of these sessions is supposed +to be the most recent real session then. +.br +Some read-only drives and media show no usable session history at all. +Eventually option -rom_toc_scan might help. +.TP +\fB\-mount_cmd\fR drive entity id path +Emit an appropriate command line for mounting the ISO session +indicated by drive, entity and id. +The result will be different on Linux and on FreeBSD. +.br +drive can be "indev" or "outdev" to indicate already aquired drives, +or it can be the path of a not yet acquired drive. +Prefix "stdio:" for non-MMC drives is not mandatory. +.br +entity must be either "sbsector" , "track" , "session" , "volid" +or "auto". See also option -load. +.br +id gives the superblock sector address, the track number, the session number, +or a search pattern for the volume id respectively. +.br +path will be used as mount point and must already exist as a directory. +.br +The command gets printed to the result channel. See option -mount +for direct execution of this command. +.TP +\fB\-session_string\fR drive entity id format +Print to the result channel a text which gets composed according to +format and the parameters of the addressed session. +.br +Formats "linux:"path or "freebsd:"path produce the output of -mount_cmd +for the given operating systems. +.br +In other texts xorriso will substitute the following parameter names. +An optional prefix "string:" will be removed. +.br +"%device%" will be substituted by the mountable device path of the drive +address. +.br +"%sbsector%" will be substituted by the session start sector. +.br +"%track%", "%session%", "%volid%" will be substituted by track number, +session number, resp. volume id of the depicted session. +.TP +\fB\-print_size\fR +Print the foreseeable consumption of 2048 byte blocks +by next -commit. This can last a while as a -commit gets +prepared and only in last moment is revoked by this option. +.TP +\fB\-tell_media_space\fR +Print available space on output media and the free space after +subtracting already foreseeable consumption by next -commit. +.TP +.B Navigation in ISO image and disk filesystem: +.TP +\fB\-cd\fR iso_rr_path +Change the current working directory in the emerging ISO +image as it is at the moment. This is prepended to iso_rr_paths +which do not begin with '/'. +.br +It is possible to set the working directory to a path which does not exist +yet in the ISO image.

The reasons may be +various and get obscured by error correction which is performed by the drives +and based on extra data on the media. If a drive returns data then one can +quite trust that they are valid. But at some degree of read problems the +correction will fail and the drive is supposed to indicate error. +.br +xorriso can scan the media for readable data blocks, classify them according +to their read speed, save them to a file, and keep track of successfuly saved +blocks for further tries on the same media. +.TP +\fB\-check_media\fR [option [option ...]] -- +Try to read data blocks from the indev drive, eventually copy them to a +disk file, and finally report about the encountered quality. Several options +may be used to modify the default behavior. +.br +The options given with this command override the default settings which +may have been changed by option -check_media_defaults. See there for a +description of options. +.br +The result list tells intervals of 2 KiB blocks with start address, number +of blocks and quality. Qualities which begin with "+" are +supposed to be valid readable data. Qualities with "-" are no valid data. +.br +Alternatively it is possible to report damaged files rather than blocks. +.TP +\fB\-check_media_defaults\fR [option [option ...]] -- +Preset options for runs of -check_media, -extract_cut and best_effort +file extraction. Eventual options given with -check_media will override the +preset options. -extract_cut will override some options automatically. +.br +An option consists of a keyword, a "=" character, and a value. Options +may override each other. So their sequence matters. +.br +The default setting at program start is: +.br +use=indev what=tracks min_lba=-1 max_lba=-1 retry=default +time_limit=28800 item_limit=100000 +.br +abort_file=/var/opt/xorriso/do_abort_check_media +.br +data_to='' sector_map='' map_with_volid=off patch_lba0=off report=blocks +.br +Option "reset=now" restores these startup defaults. +.br +Non-default options are: +.br +"report=files" lists the files which use damaged blocks (not with use=outdev). +The format is like with find -exec report_damage. +.br +"report=blocks_files" first lists damaged blocks and then affected files. +.br +"use=outdev" reads from the output drive instead of the input drive. This +avoids loading the ISO image tree from media. +.br +"what=disc" scans the payload range of a media without respecting track gaps. +.br +"min_lba=" omits all blocks with addresses lower than the option value. +.br +"max_lba=" switches to what=disc and omits all blocks above its option value. +.br +"retry=on" forces read retries with single blocks when the normal read +chunk produces a read error. By default, retries are only enabled with CD +media. "retry=off" forbits retries for all media types. +.br +"abort_file=" gives the path of the file which may abort a scan run. Abort +happens if the file exists and its mtime is not older than the start time +of the run. Use shell command "touch" to trigger this. +Other than an aborted program run, this will report the tested and untested +blocks and go on with running xorriso. +.br +"time_limit=" gives the number of seconds after which the scan shall be +aborted. This is useful for unattended scanning of media which may else +overwork the drive in its effort to squeeze out some readable blocks. +Abort may be delayed by the drive gnawing on the last single read operation. +Value -1 means unlimited time. +.br +"item_limit=" gives the number of report list items after which to abort. +Value -1 means unlimited item number. +.br +"data_to=" copies the valid blocks to the file which is given as option value. +.br +"sector_map=" tries to read the file given by option value as +sector bitmap and to store such a map file after the scan run. +The bitmap tells which blocks have been read successfully in previous runs. +It allows to do several scans on the same media, eventually with intermediate +eject, in order to collect readable blocks whenever the drive is lucky enough +to produce them. The stored file contains a human readable TOC of tracks +and their start block addresses, followed by binary bitmap data. +.br +"map_with_volid=on" examines tracks whether they are ISO images and eventually +prints their volume ids into the human readable TOC of sector_map=. +.br +"patch_lba0=on" transfers within the data_to= file a copy of the currently +loaded session head to the start of that file and patches it to be valid +at that position. +This makes the loaded session the default session of the image file +when it gets mounted or loaded as stdio: drive. But it usually makes +the original session 1 inaccessible. +.br +"patch_lba0=force" performs "patch_lba0=on" even if xorriso believes +that the copied data are not valid. +.br +"patch_lba0=" may also bear a number. If it is 32 or higher it is taken as +start address of the session to be copied. In this case it is not necessary to +have an -indev and a loaded image. ":force" may be appended after the number. +.br +"use=sector_map" does not read any media but loads the file given by option +sector_map= and processes this virtual outcome. +.TP +.B osirrox restore options: +.PP +Normally xorriso only writes to disk files which were given as stdio: +pseudo-drives or as log files. +But its alter ego, osirrox, is able to extract file objects +from ISO images and to create, overwrite, or delete file objects on disk. +.br +Disk file exclusions by -not_mgt, -not_leaf, -not_paths apply. +If disk file objects already exist then the settings of -overwrite and +-reassure apply. But -overwrite "on" only triggers the behavior +of -overwrite "nondir". I.e. directories cannot be deleted. +.br +Access permissions of files in the ISO image do not restrict restoring. +The directory permissions on disk have to allow rwx. +.TP +\fB\-osirrox\fR "on"|"device_files"|"off"[:option:...] +Setting "off" disables disk filesystem manipulations. This is the default +unless the program was started with leafname "osirrox". Elsewise +the capability to restore files can be enabled explicitly by -osirrox "on". +.br +To enable restoring of special files by "device_files" is potentially +dangerous. +The meaning of the number st_rdev (see man 2 stat) depends much on the +operating system. Best is to restore device files only to the same system +from where they were copied. If not enabled, device files in the ISO image +are ignored during restore operations. +.br +Due to a bug of previous versions, device files from previous sessions might +have been altered to major=0, minor=1. So this combination does not get +restored. +.br +Option "concat_split_on" is default. It enables restoring of split file +directories as data files if the directory contains a complete collection +of -cut_out part files. With option "concat_split_off" such directories are +handled like any other ISO image directory. +.br +Option "auto_chmod_off" is default. If "auto_chmod_on" is set then access +restrictions for disk directories get circumvented if those directories +are owned by the effective user who runs xorriso. This happens by temporarily +granting rwx permission to the owner. It will not work with ACL restrictions. +.TP +\fB\-extract\fR iso_rr_path disk_path +Restore the file objects at and underneath iso_rr_path to their corresponding +addresses at and underneath disk_path. +This is the inverse of -map or -update_r. +.br +If iso_rr_path is a directory and disk_path is an existing directory then +both trees will be merged. Directory attributes get extracted only if the disk +directory is newly created by the restore operation. +Disk files get removed only if they are to be replaced +by file objects from the ISO image. +.br +As many attributes as possible are copied together with restored +file objects. +.TP +\fB\-extract_single\fR iso_rr_path disk_path +Like -extract, but if iso_rr_path is a directory then its sub tree gets not +restored. +.TP +\fB\-extract_l\fR iso_rr_prefix disk_prefix iso_rr_path [***] +Perform -extract with each of the iso_rr_path arguments. disk_path will be +composed from iso_rr_path by replacing iso_rr_prefix by disk_prefix. +.TP +\fB\-extract_cut\fR iso_rr_path byte_offset byte_count disk_path +Copy a byte interval from a data file out of an ISO image into a newly created +disk file. +Two restrictions apply: +.br +The data bytes of iso_rr_path need to be already stored in the loaded ISO image +and byte_offset must be a multiple of 2048, e.g. an integer with suffix +s, m, or g. +.br +This option is implemented by a special run of -check_media and governed by +most of the options which can be set by -check_media_defaults. +Its main purpose is to allow handling of large files if they are not supported +by mount -t iso9660 and if the reading system is unable to buffer them as +a whole. +.TP +\fB\-cpx\fR iso_rr_path [***] disk_path +Extract single leaf file objects from the ISO image and store them under +the address given by disk_path. If more then one iso_rr_path is given then +disk_path must be a directory or non-existent. In the latter case it gets +created and the extracted files get installed in it with the same leafnames. +.br +Missing directory components in disk_path will get created, if possible. +.br +Directories are allowed as iso_rr_path only with -osirrox "concat_split_on" +and only if they actually represent a complete collection of -cut_out split +file parts. +.TP +\fB\-cpax\fR iso_rr_path [***] disk_path +Like -cpx but restoring mtime, atime as in ISO image and trying to set +ownership and group as in ISO image. +.TP +\fB\-cp_rx\fR iso_rr_path [***] disk_path +Like -cpx but also extracting whole directory trees from the ISO image. +.br +The resulting disk paths are determined as with shell command cp -r : +If disk_path is an existing directory then the trees will be inserted or merged +underneath this directory and will keep their leaf names. The ISO directory "/" +has no leaf name and thus gets mapped directly to disk_path. +.TP +\fB\-cp_rax\fR iso_rr_path [***] disk_path +Like -cp_rx but restoring mtime, atime as in ISO image and trying to set +ownership and group as in ISO image. +.TP +\fB\-paste_in\fR iso_rr_path disk_path byte_offset byte_count +Read the content of a ISO data file and write it into a data file on disk +beginning at the byte_offset.

For safety reasons the mount program is only executed if it is +reachable as /bin/mount or /sbin/mount. +.TP +.B Command compatibility emulations: +.PP +Writing of ISO 9660 on CD is traditionally done by program mkisofs +as ISO 9660 image producer and cdrecord as burn program. +xorriso does not strive for their comprehensive emulation. +Nevertheless it is ready to perform some of its core tasks under control +of commands which in said programs trigger comparable actions. +.TP +\fB\-as\fR personality option [options] -- +.br +Perform its variable length option list as sparse emulation of the program +depicted by the personality word. +.br + +Personality "\fBmkisofs\fR" accepts the options listed with: +.br + -as mkisofs -help -- +.br +Among them: -R (always on), -J, -o, -M, -C, -path-list, -m, -exclude-list, +-f, -print-size, -pad, -no-pad, -V, -v, -version, -graft-points, +-no-emul-boot, -b, -c, -boot-info-table, -boot-load-size, -input-charset, +-output-charset, pathspecs as with xorriso -add. +A lot of options are not supported and lead to failure of the mkisofs +emulation. Some are ignored, but better do not rely on this tolerance. +.br +-graft-points is equivalent to -pathspecs on. Note that pathspecs without "=" +are interpreted differently than with xorriso option -add. Directories get +merged with the root directory of the ISO image, other filetypes get mapped +into that root directory. +.br +Other than with the "cdrecord" personality there is no automatic -commit at +the end of a "mkisofs" option list. Verbosity settings -v (= "UPDATE") and +-quiet (= "SORRY") persist. The output file, eventually chosen with -o, +persists until things happen like -commit, -rollback, -dev, or end of xorriso. +-pacifier gets set to "mkisofs" if files are added to the image. +.br +If pathspecs are given and if no output file was chosen before or during the +"mkisofs" option list, then standard output (-outdev "-") will get into effect. +If -o points to a regular file, then it will be truncated to 0 bytes +when finally writing begins. This truncation does not happen if the drive +is chosen by xorriso options before or after -as mkisofs. +Directories and symbolic links are no valid -o targets. +.br +Writing to stdout is possible only if -as "mkisofs" was among the start +arguments or if other start arguments pointed the output drive to +standard output. +.br +Not original mkisofs options are --quoted_path_list (see -quoted_path_list) +and isolinux_mbr= (see -boot_image isolinux isohybrid=). +.br +Personalites "\fBxorrisofs\fR", "\fBgenisoimage\fR", and "\fBgenisofs\fR" +are aliases for "mkisofs". +.br +If xorriso is started with one of the leafnames "xorrisofs", "genisofs", +"mkisofs", or "genisoimage", then it automatically prepends -as "genisofs" +to the command line arguments. I.e. all arguments will be interpreted mkisofs +style until "--" is encountered. From then on, options are interpreted +as xorriso options. +.br + +Personality "\fBcdrecord\fR" accepts the options listed with: +.br + -as cdrecord -help -- +.br +Among them: -v, dev=, speed=, blank=, fs=, -eject, -atip, padsize=, tsize=, +-isosize, -multi, -msinfo, --grow_overwriteable_iso, write_start_address=, +track source file path or "-" for standard input as track source. +.br +It ignores most other options of cdrecord and cdrskin but refuses on +-audio, -scanbus, and on blanking modes unknown to xorriso. +.br +The scope is only a single data track per session to be written +to blank, overwriteable, or appendable media. The media gets closed if +closing is applicable and not option -multi is present. +.br +An eventually aquired input drive is given up. +This is only allowed if no image changes are pending. +.br +dev= must be given as xorriso device address. Adresses like 0,0,0 or ATA:1,1,0 +are not supported. +.br +If a track source is given, then an automatic -commit happens at the end of +the "cdrecord" option list. +.br +--grow_overwriteable_iso enables emulation of multi-session on overwriteable +media. To enable emulation of a TOC, the first session needs -C 0,32 with +-as mkisofs (but no -M) and --grow_overwriteable_iso write_start_address=32s +with -as cdrecord. +.br +A much more elaborate libburn based cdrecord emulator is the program cdrskin. +.br +Personalites "\fBxorrecord\fR", "\fBwodim\fR", and "\fBcdrskin\fR" are aliases +for "cdrecord". +.br +If xorriso is started with one of the leafnames "xorrecord", "cdrskin", +"cdrecord", or "wodim", then it automatically prepends -as "cdrskin" +to the command line arguments.

ISO 9660 Rock Ridge Filesystem Manipulator for Linux and FreeBSD

+
+ +

+

Purpose:

+xorriso copies file objects from POSIX compliant filesystems +into Rock Ridge enhanced ISO 9660 filesystems and allows +session-wise manipulation of such filesystems. It can load the management +information of existing ISO images and it writes the session results to +optical media or to filesystem objects. +
+Vice versa xorriso is able to restore file objects from ISO 9660 filesystems. +

+

+

Hardware requirements:

+A CD/DVD/BD recorder suitable for +http://libburnia-project.org
+(SCSI , ATA , USB , or SATA writers compliant to standard MMC-3 for CD +and to MMC-5 for DVD or BD). +
+

+ +

+

Software requirements :

+
+
Linux with kernel 2.4 or higher (and libc, of course) :
+
With kernel 2.4 an ATA drive has to be under ide-scsi emulation.
+
With kernel 2.6 the drive should not be under ide-scsi.
+
or FreeBSD (with libc, of course) :
+
ATAPI/CAM support has to be enabled in the kernel, see atapicam(4).
+
libpthread
+
is supposed to be a standard system component.
+
libreadline and libreadline-dev
+
are optional and eventually make dialog more convenient.
+
+

+ +

+

+GPL software included:
+

+
+
libburn-0.5.7

    • + +
+

+ +

+

Command Examples:

+
+
Get an overview of drives and their addresses
+
# xorriso -devices
+
...
+
0 -dev '/dev/sr0' rwrw-- : 'TSSTcorp' 'CDDVDW SH-S203B'
+
1 -dev '/dev/scd1' rwrw-- : 'PHILIPS ' 'SPD3300L'
+
2 -dev '/dev/hda' rwrw-- : 'HL-DT-ST' 'DVD-ROM GDR8162B'
+
...
+
Being superuser avoids permission problems with /dev/srN resp. /dev/hdX . +
+
Ordinary users should then get granted rw access to the /dev files +as listed by option -devices.
+
 
+ +
Options are either performed as program arguments or as dialog input. +Some options have a parameter list of variable length. This list has to +be terminated by word '--' or by the end of the input line. Option -add +may accept pathspecs of form target=source as known from program mkisofs.
+ +
+ +
Get info about a particular drive and loaded media:
+
$ xorriso -indev /dev/sr0 -du / -- -toc 2>&1 | less
+ +
Make re-usable media writable again, delete any ISO 9660 image, +eventually prepare yet unused BD-RE:
+
$ xorriso -outdev /dev/sr0 -blank as_needed -eject all
+ +
+
+
+ +
Write some directories into a new or existing ISO 9660 image:
+
$ xorriso -dev /dev/sr0 -add /home/me/sounds /home/me/pictures +
+ +
Have a look at the result:
+
$ xorriso -indev /dev/sr0 -du / -- -toc 2>&1 | less
+ +
+
+
+ +
Create new ISO-9660 filesystem image, compose content, +adjust permissions to make it publicly read-only, +write it to media and immediately eject media without +previously reloading the written image. +
+
$ cd /home/me
+
$ xorriso -outdev /dev/sr0 -blank as_needed \
+
  -map /home/me/sounds /sounds \
+
  -map /home/me/pictures /pictures \
+
  -rm_r /sounds/indecent '/pictures/*private*' -- \
+
  -cd / \
+
  -add pictures/private/horses* -- \
+
  -chmod_r a+r,a-w / -- \
+
  -find / -type d -exec chmod a+x -- \
+
  -volid SOUNDS_PICS_2008_01_16 \
+
  -commit_eject all
+
+
+
+ +
Load the previous session from media, +remove (i.e. hide) directory /sounds, +rename /pictures/private/horses, +add new directory trees /sounds and /movies, +disallow any access for group and others. +Finally write as additional session to media and eject:
+
$ xorriso -dev /dev/sr0 \
+
  -rm_r /sounds -- \
+
  -mv /pictures/private/horses /horse_show -- \
+
  -map /home/me/prepared_for_dvd/sounds_dummy /sounds \
+
  -map /home/me/prepared_for_dvd/movies /movies \
+
  -chmod_r go-rwx / -- \
+
  -volid SOUNDS_PICS_2008_01_17 \
+
  -commit_eject all
+
+
+
+ +
Merge the various sessions from old readable media into a single session +on new writeable media, +cleaning out all invalidated files and session overhead. +Touch / in order to mark the image as worth to be written. +
+Important: -indev and -outdev have to be different drives. +
+
$ xorriso -indev /dev/dvd \
+
  -alter_date a +0 / -- \
+
  -outdev /dev/sr0 -blank fast \
+
  -commit_eject all
+ +
+
+
+ +
Dialog mode accepts one or more options per line. An option and all its +arguments have to be given in one single line. Command -end stops the program +run. It will write eventually pending changes to media, if that has not +already been done by a previous -commit.
+
$ xorriso -dialog on
+
enter option and arguments :
+
-dev /dev/sr0
+
enter option and arguments :
+
-map /home/me/prepared_for_dvd/sounds_dummy /sounds
+
enter option and arguments :
+
-map /home/me/prepared_for_dvd/movies /movies
+
Available navigation commands: -cd, -ls, -du, -find
+
enter option and arguments :
+
-commit
+
... perform further commands and finally do:
+
enter option and arguments :
+
-end
+ +
+
+
+ +
The following command can be run on blank media to create a +copy of the mentioned disk directory trees, and it can be run on appendable +media to perform a minimal set of change operations which update the +old ISO copies to match the new disk trees. +Older states can be retrieved by help of mount option "session=" from CD-R[W], +by help of "sbsector=" from other media. +So this constitutes true incremental backup. +
+The copies will be complete, except all file names ending +with ".o" or ".swp" which are excluded by options -not_leaf. +
+
$ xorriso -dev /dev/sr0 \
+
   -volid PROJECTS_MAIL_"$(date '+%Y_%m_%d_%H%M%S')" \
+
   -not_leaf '*.o' -not_leaf '*.swp' \
+
   -update_r /home/thomas/open_source_projects /open_source_projects \
+
   -update_r /home/thomas/personal_mail /personal_mail \
+
   -commit -toc -eject all
+ +
+
+
+ +
+After the user has already created a suitable file tree on disk +and copied the ISOLINUX files into subdirectory ./boot/isolinux of +that tree, xorriso can burn an El Torito bootable media: +
+
$ xorriso -outdev /dev/sr0 -blank as_needed \
+
   -map /home/me/ISOLINUX_prepared_tree / \
+
   -boot_image isolinux dir=/boot/isolinux
+
+An additional MBR is generated if the file isolinux.bin is modern enough +(syslinux version 3.72) and ready for "isohybrid". An MBR enables booting +from hard disk or USB stick. +
+
+ +
ISO images may not only be stored on optical media but also in +regular disk files or block devices for full multi-session operation. +The prefix "stdio:" indicates that normal file operations are +desired rather than MMC drive commands: +
+
$ xorriso -dev stdio:/tmp/regular_file ...other.options...
+ +
Other file types are suitable only for writing but not for reading:
+
$ xorriso -outdev stdio:/tmp/named_pipe ...other.options...
+ +
In batch mode it is possible to operate xorriso in a pipeline +with an external consumer of the generated ISO image. Any message +output will be redirected to stderr in this case.
+
$ xorriso -outdev - ...other.options... | consumer
+ + +
+
+
+ +
+Let xorriso serve underneath growisofs via its alias name "xorrisofs" +which enables mkisofs emulation: +
+
$ export MKISOFS="xorrisofs"
+
$ growisofs -Z /dev/dvd /some/files
+
$ growisofs -M /dev/dvd /more/files
+
+One may switch from mkisofs emulation to xorriso's own command mode: +
+
$ growisofs -M /dev/dvd -- outdev - -update_r /my/files /files +
+ +
+
+
+ +
If for any reason the reading operating system mishandles the ISO image +or some files in it, one may enable reverse operation of xorriso and copy +files or trees to disk: +
$ xorriso -indev /dev/sr0 \
+
   -osirrox on \
+
   -cpx '/pictures/private/horses*/*buttercup*' \
+
       /home/her/buttercup_dir -- \ +
   -extract /sounds /home/her/sounds_from_me
+ +
Consider to enter dialog mode and use commands like +-cd , -du , -lsl , -find. +

If you want to distribute development versions of xorriso, then use +this tarball which produces static linking between xorriso and the +libburnia libraries. +
+
Source (./bootstrap is already applied, build tested, +installation see README) +
+
+xorriso-0.3.1.tar.gz +(1080 KB). +
+
A dynamically linked development version of xorriso can be obtained +from repositories of + libburnia-project.org. +xorriso is part of libisoburn/trunk and will get built by its "make". +
+
Be warned that the libraries in SVN and bzr are development versions with +possibly unstable API/ABI enhancements. Do not distribute development +versions for dynamic linking. Only release versions are safe for that. +
+
Download: svn co http://svn.libburnia-project.org/libburn/trunk libburn +
+
Install: cd libburn ; ./bootstrap ; ./configure --prefix /usr ; make ; make install +
+
Download: bzr branch lp:libisofs
+
Install: cd libisofs ; ./bootstrap ; ./configure --prefix /usr ; make ; make install +
+
Download: svn co http://svn.libburnia-project.org/libisoburn/trunk libisoburn +
+
Install: cd libisoburn ; ./bootstrap ; ./configure --prefix /usr ; make ; make install +
+
Build of SVN versions needs +autotools of at least version 1.7 installed. +But after the run of ./bootstrap, only +vanilla tools like make and gcc are needed. +
