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-0.4.5

reads and writes data from and to CD and DVD.

(founded by Derek Foreman and Ben Jansens, furthered since August 2006 by team of libburnia-project.org)

libisofs-0.6.4

operates ISO 9660 images.

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

libisoburn-0.1.4

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 or DVD are fixely integrated.
• Operates on an existing ISO image or creates a new one.
• Copies files from filesystem into the ISO image.
• Renames or deletes file objects in the ISO image.
• Changes file properties in the ISO image.
• Updates ISO subtrees incrementally to match given disk subtrees.
• Can write result as completely new image to optical media or filesystem objects.
• Can write result as add-on session to appendable multi-session media, to overwriteable media, to regular files, and to block devices.
• Scans for optical drives, blanks re-useable optical media.
• Suitable for: CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+R/DL, DVD+RW, DVD-RAM.
• Reads its instructions from command line arguments, dialog, and batch files.
• Provides navigation commands for interactive ISO image manipulation.
• Adjustable thresholds for abort, exit value, and problem reporting.

Command Examples:

Get an overview of drives and their addresses

# xorriso -devices

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:

$ xorriso -outdev /dev/sr0 -blank fast -eject all

---

Write some directories into a new or existing ISO 9660 image:

$ xorriso -dev /dev/sr0 -add /home/me/sounds /home/me/pictures

Check 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.

$ xorriso -outdev /dev/sr0 -blank fast -pathspecs on \

  -add /sounds=/home/me/sounds \

       /pictures=/home/me/pictures -- \

  -rm_r /sounds/indecent '/pictures/*private*' -- \

  -add /pictures/private/horses=/home/me/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 -pathspecs on \

  -rm_r /sounds -- \

  -mv /pictures/private/horses /horse_show -- \

  -add /sounds=/home/me/prepared_for_dvd/sounds_dummy \

       /movies=/home/me/prepared_for_dvd/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 -pathspecs on

enter option and arguments :

-add /sounds=/home/me/prepared_for_dvd/sounds_dummy /movies=/home/me/prepared_for_dvd/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 complete 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 DVD-R[W] and DVD+R. So this constitutes true incremental backup. On overwriteable media only the newest state is accessible.

$ xorriso -dev /dev/sr0 \

   -volid PROJECTS_MAIL_"$(date '+%Y_%m_%d_%H%M%S')" \

   -update_r /home/thomas/open_source_projects /open_source_projects \

   -update_r /home/thomas/personal_mail /personal_mail \

   -commit -toc -eject all

---

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

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-0.1.5.tar.gz (970 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.
