<H1>GNU xorriso</H1>

<H2>ISO 9660 Rock Ridge Filesystem Manipulator<BR>
for GNU/Linux, FreeBSD, Solaris, NetBSD</H2>
</P>
</CENTER>

<P>
<H2>Purpose:</H2>
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.
<BR>
Vice versa xorriso is able to copy file objects out of ISO 9660 filesystems.

<H2>Hardware requirements:</H2>
About any CD, DVD, or BD recorder produced in the recent ten years.
<BR>
<A HREF="http://libburnia-project.org">libburn</A>
supports recorders which are compliant to standards MMC-1 for CD and
MMC-5 for DVD or BD.
<BR>
GNU/Linux, FreeBSD, Solaris, NetBSD provide access to drives connected
via SCSI, PATA (aka IDE, ATA), USB, or SATA.
<BR>
xorriso also operates on ISO images in data files or block devices.
Images or add-on sessions may be written to about any kind of file object.
</P>

<P>
<H2>Software requirements :</H2>
<DL>
<DT>GNU/Linux with kernel 2.4 or higher, libc, libpthread :</DT>
<DD>With kernel 2.4 a PATA/IDE drive has to be under ide-scsi emulation.</DD>
<DD>Since kernel 2.6 ide-scsi is not needed.</DD>
<DT>or FreeBSD, libc, libpthread, libcam, libiconv :</DT>
<DD>PATA/IDE drives need atapicam running.</DD>
<DD>SATA drives need atapicam running or need to be driven by ahci.</DD>
<DT>or Solaris, libc, libpthread, libvolmgt :</DT>
<DD>Tested on kernel 5.11, hopefully suitable for older ones too.</DD>
<DT>or NetBSD, libc, libpthread :</DT>
<DD>Tested on 6.1.2 and 6.1.3, hopefully suitable for older ones too.</DD>
<DT>or some other X/Open system, libc, libpthread :</DT>
<DD>
There will be no direct operation of optical drives, but only POSIX i/o
with objects of the local filesystem.
</DD>
<DD>
Might work with DVD-RAM, DVD+RW, BD-RE
but rather not with CD, DVD-R, DVD+R, BD-R.
</DD>
</DL>

<H3>Optional supporting software:</H2>
<DL>
<DT>libreadline and libreadline-dev</DT>
<DD>make dialog more convenient.</DD>
<DT>libacl and libacl-devel</DT>
<DD>allow on GNU/Linux to get and set ACLs.</DD>

<P>
Note that xorriso does not write audio CDs and that it does not
produce UDF filesystems which are specified for official video DVD or BD.
</P>

<P>
<H2>GUI Frontend:</H2>
xorriso itself is entirely controlled by text commands. In dialog mode,
xorriso reads them as text lines from standard input.
Together with some helpful xorriso commands, it is quite easy for frontend
programs to operate a separate xorriso process.
<BR>
Other than the usual batch programs, xorriso will take care of maintaining
the emerging ISO image model. Its state can be inquired by the frontend
at any time. The frontend is supposed to care for the display of the inquired
xorriso state and to send xorriso commands to manipulate the ISO image model.
<BR>
As a proof of concept, there is a Tcl/Tk script which can
be launched by shell command <KBD>xorriso-tcltk</KBD>
<BR>

</A>
<BR>
The script <KBD>xorriso-tcltk</KBD>
is part of the tarball and gets installed by <KBD>make install</KBD>. If a
xorriso distro package does not install it, you may get it directly from
<A HREF="https://dev.lovelyhq.com/libburnia/libisoburn/raw/master/frontend/xorriso-tcltk">
libburnia git: libisoburn/frontend/xorriso-tcltk
</A>
You will probably have to give it x-permission after download. Some browsers
insist in adding &quot;.htm&quot; to the file name.
<BR>
Further you need xorriso >= 1.5.4, Tcl, Tk >= 8.4,
Tcl/Tk package &quot;BWidget&quot;.

<DT>Being superuser avoids permission problems with /dev/srN resp. /dev/hdX .
</DT>
<DT>
Ordinary users should then get granted access to the /dev files
as listed by option --devices. GNU/Linux, FreeBSD, NetBSD demand rw-permission.
On Solaris it is r-permission and privileges "basic,sys_devices".
</DT>
<DT>&nbsp;</DT>

<DT>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.</DT>

<DT>The following command performs incremental backup.
It 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 options like "sbsector="
or by help of xorriso option -mount.
<BR>
Eventual ACL, xattr and hardlink relations will be recorded. MD5 checksums
will be computed and recorded. Data comparison will be avoided by accelerator
option -disk_dev_ino. After writing, the new session will be checked
by its recorded MD5.
<BR>
Only blank media or media with volume id "PROJECTS_MAIL_..." will be accepted.
Files with names ending by ".o" or ".swp" are excluded by options -not_leaf.
</DT>
<DD>$<KBD>&nbsp;xorriso -for_backup -disk_dev_ino on \</KBD></DD>

<DD><KBD>&nbsp;&nbsp; -commit -toc -check_md5 FAILURE -- -eject all</KBD></DD>

<DT>
To apply zisofs compression to those data files which get newly copied from
the local filesystem, perform immediately before -commit :
<DD><KBD>&nbsp;&nbsp; -hardlinks perform_update \</KBD></DD>
<DD>
<KBD>&nbsp;&nbsp; -find / -type f -pending_data -exec set_filter --zisofs -- \</KBD></DD>

<DT>
Operating systems usually mount the most recent session on media.
xorriso can issue the appropriate mount commands for older sessions.
First get an overview of the sessions on the media:
</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -toc</KBD></DD>
<PRE>
TOC layout   : Idx ,  sbsector ,       Size , Volume Id
ISO session  :   1 ,         0 ,    104719s , PROJECTS_MAIL_2008_08_10_231435
ISO session  :   2 ,    106928 ,      6785s , PROJECTS_MAIL_2008_08_14_184548
...
ISO session  :  76 ,    820384 ,     11035s , PROJECTS_MAIL_2009_01_04_191150
</PRE>

<DT>
Then become superuser and let xorriso mount the session of August 14, 2008
to directory /mnt:
</DT>
<DD>#<KBD>
&nbsp;xorriso -osirrox on -mount /dev/sr0 volid '*_2008_08_14_*' /mnt
</KBD></DD>
<DT>
To be later unmounted by: <KBD>umount /mnt</KBD>
</DT>

<DT>
<HR>
</DT>

<DT>
For creating bootable ISO images with GRUB2, use its script
<KBD>grub-mkrescue</KBD> which knows how to operate xorriso.
</DT>

<DT>
<HR>
</DT>

<DT>
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:
</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -blank as_needed \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -map /home/me/ISOLINUX_prepared_tree / \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -boot_image isolinux dir=/boot/isolinux</KBD></DD>
<DT>
An MBR may be added if the file isolinux.bin is modern enough for "isohybrid"
(syslinux version 3.72). It enables booting from hard disk or USB stick:
</DT>
<DD><KBD>&nbsp;&nbsp; -boot_image isolinux system_area=mbr/isohdpfx.bin \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -boot_image isolinux partition_table=on \</KBD></DD>
<DT>
<HR>
</DT>

<DT>ISO images may not only be stored on optical media but also in
regular disk files or block devices for full multi-session operation.
</DT>
<DD>$<KBD>&nbsp;xorriso -dev /tmp/regular_file ...other.options...</DD>
<DT>
A default setting for safety reasons requires that files below /dev/
need prefix &quot;stdio:&quot; if they do not lead to MMC burner devices.
Be cautious not to overwrite your hard disk instead of your USB stick:
</DT>
<DD>$<KBD>&nbsp;xorriso -dev stdio:/dev/sdb ...other.options...</DD>

<DT>Other file types are suitable only for writing but not for reading:</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /tmp/named_pipe ...other.options...</DD>

<DT>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.
Examples for consumers are cdrecord or growisofs on operating systems
where xorriso cannot operate the burner drive directly,
or a ssh pipe to another system which has the desired drive
and a suitable burn program.</DT>
<DD>$<KBD>&nbsp;xorriso -outdev - ...other.options... | consumer</KBD></DD>


<DT>
<HR>
</DT>

<DT>
Let xorriso serve underneath growisofs via its alias name "xorrisofs"
which enables mkisofs emulation:
</DT>
<DD>$<KBD>&nbsp;export MKISOFS="xorrisofs"</KBD></DD>
<DD>$<KBD>&nbsp;growisofs -Z /dev/dvd /some/files</KBD></DD>
<DD>$<KBD>&nbsp;growisofs -M /dev/dvd /more/files</KBD></DD>
<DT>
One may switch from mkisofs emulation to xorriso's own command mode:
</DT>
<DD>$<KBD>&nbsp;growisofs -M /dev/dvd -- outdev - -update_r /my/files /files
</KBD></DD>

<DT>
<HR>
</DT>

<DT>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:
</DT>
<DD>$<KBD>&nbsp;xorriso -acl on -xattr on \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -indev /dev/sr0 \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -osirrox on \</KBD></DD>

</DD>
<DD><KBD>&nbsp;&nbsp; -extract /sounds /home/her/sounds_from_me</KBD></DD>
<DT>Consider to enter dialog mode and use commands like

GNU xorriso is feature-wise equivalent to the dynamic compilation of
<A HREF="http://libburnia-project.org/"> libburnia </A>
libraries, libjte, and libburnia program xorriso.
It restricts itself to a technical form where the legal commitments of the
libburnia project and the legal intentions of
<A HREF="http://www.fsf.org/"> FSF </A> match completely.

<DT>A dynamically linked development version of xorriso can be obtained
from repositories of
<A HREF="http://libburnia-project.org"> libburnia-project.org</A>.
xorriso is part of libisoburn/trunk and will get built by its "make".
</DT>

<DT>Be warned that the libraries in git are development versions with
possibly unstable API/ABI enhancements. Do not distribute development
versions for dynamic linking. Only release versions are safe for that.

<DD>Download: <KBD><B>git clone https://dev.lovelyhq.com/libburnia/libburn.git</B>
</KBD></DD>
<DD>Install: <KBD><B>cd libburn ; ./bootstrap ; ./configure --prefix /usr ; make ; make install</B>

<DD>Download:
<KBD><B>git clone https://dev.lovelyhq.com/libburnia/libisofs.git</B></KBD>

</KBD></DD>
<DD>Install: <KBD><B>cd libisoburn ; ./bootstrap ; ./configure --prefix /usr ; make ; make install</B>
</KBD></DD>
<DT>Build of git versions needs autotools of at least version 1.7 installed.
But after the run of <KBD>./bootstrap</KBD>, only
vanilla tools like make and gcc are needed.
</DT>
<DT>GNU xorriso contains a copy of libjte-1.0.0 or 2.0.0 from package jigit
which produces jigdo and template file together with the emerging ISO image.
(By Free Software Foundation, Steve McIntyre, George Danchev,
Thomas Schmitt)
</DT>
<DD>Important: If desired, libjte has to be already installed when libisofs
and libisoburn get built.</DD>

Very special thanks to Andy Polyakov whose 
<A HREF="http://fy.chalmers.se/~appro/linux/DVD+RW/tools">dvd+rw-tools</A>
provide the libburnia project with invaluable examples on how to deal
with DVD media and how to emulate multi-session on overwritable media.
