xorriso

Purpose:

Hardware requirements:

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.

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-0.5.5

reads and writes data from and to CD, DVD, BD-RE.

(founded by Derek Foreman and Ben Jansens, developed and maintained since August 2006 by Thomas Schmitt from team of libburnia-project.org)

libisofs-0.6.10

operates on ISO 9660 filesystem images.

(By Vreixo Formoso and Mario Danic from team of libburnia-project.org)

libisoburn-0.2.8

coordinates libburn and libisofs, emulates multi-session where needed.

(By Vreixo Formoso and Thomas Schmitt from team of libburnia-project.org)

This program system has been tested on Intel/AMD Linux systems only.
For ports to other usable systems contact us.

Special features:

• ISO 9660 formatter and burner for CD, DVD, BD-RE are fixely integrated.
• Operates on an existing ISO image or creates a new one.
• Copies files from filesystem into the ISO image.
• Changes file properties, renames or deletes file objects in the ISO image.
• Updates ISO subtrees incrementally to match given disk subtrees.
• Writes result as completely new image or as add-on session to optical media or filesystem objects.
• Can activate ISOLINUX boot images by El Torito boot record.
• Can perform multi-session tasks as emulation of mkisofs and cdrecord.
• Can restore single files and whole trees from ISO image to disk filesystem.
• Can check media for damages and copy readable blocks to disk.
• Scans for optical drives, blanks re-useable optical media, formats media.
• Suitable for: CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+R DL, DVD+RW, DVD-RAM, BD-RE.
• Reads its instructions from command line arguments, dialog, and batch files.
• Provides navigation commands for interactive ISO image manipulation.

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

---

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-0.2.9.tar.gz (1050 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.

 

Many thanks to Derek Foreman and Ben Jansens for starting libburn.
Very special thanks to Andy Polyakov whose dvd+rw-tools provide the libburnia project with invaluable examples on how to deal with DVD media and how to emulate multi-session on overwriteable media.
