<H2>ISO 9660 Rock Ridge Filesystem Manipulator for Linux and FreeBSD</H2>
</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 restore file objects from ISO 9660 filesystems.

<H2>Hardware requirements:</H2>
A CD/DVD/BD recorder suitable for
<A HREF="http://libburnia-project.org">http://libburnia-project.org</A> <BR>
(SCSI , ATA , USB , or SATA writers compliant to standard MMC-3 for CD
and to MMC-5 for DVD or BD).
<BR>
</P>
<P>
<H2>Software requirements :</H2>
<DL>
<DT>Linux with kernel 2.4 or higher, libc, libpthread :</DT>
<DD>With kernel 2.4 an ATA drive has to be under ide-scsi emulation.</DD>
<DD>With kernel 2.6 the drive should not be under ide-scsi.</DD>
<DT>or FreeBSD, libc, libpthread :</DT>
<DD>ATAPI/CAM support has to be enabled in the kernel, see atapicam(4).</DD>
<DD>libcam has to be installed.</DD>
<DD>libiconv has to be installed.</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>eventually make dialog more convenient.</DD>
<DT>libacl and libacl-devel</DT>
<DD>eventually allow on Linux to get and set ACLs.</DD>
<DT>zlib and zlib-devel</DT>
<DD>eventually allow zisofs and gzip compression.</DD>

<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 or xattr will be recorded. Data reading will be avoided by
accelerator option -disk_dev_ino.
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 -acl on -xattr on -disk_dev_ino on \</KBD></DD>
<DD><KBD>&nbsp;&nbsp; -assert_volid 'PROJECTS_MAIL_*' FATAL \</KBD></DD>

<DD><KBD>&nbsp;&nbsp; -commit -toc -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; -find / -type f -pending_data -exec set_filter --zisofs -- \</KBD></DD>
</DD>
</DT>
<DT>
<HR>
</DT>
<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>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -toc</KBD></DD>
<PRE>
TOC layout : Idx , sbsector , Size , Volume Id
ISO session : 1 , 0 , 104719s , PROJECTS_MAIL_2008_08_10_231435
ISO session : 2 , 106928 , 6785s , PROJECTS_MAIL_2008_08_14_184548
...
ISO session : 76 , 820384 , 11035s , PROJECTS_MAIL_2009_01_04_191150
</PRE>
<DT>
Then become superuser and let xorriso mount the session of August 14, 2008
to directory /mnt:
</DT>
<DD>#<KBD>
&nbsp;xorriso -osirrox on -mount /dev/sr0 volid '*_2008_08_14_*' /mnt
</KBD></DD>
<DT>
To be later unmounted by: <KBD>umount /mnt</KBD>
</DT>
<DT>
<HR>
</DT>
<DT>
After the user has already created a suitable file tree on disk
and copied the ISOLINUX files into subdirectory ./boot/isolinux of
that tree, xorriso can burn an El Torito bootable media:
</DT>
<DD>$<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 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.
<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:
<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><KBD>&nbsp;&nbsp; -cpx '/pictures/private/horses*/*buttercup*' \</KBD></DD>
<DD><KBD>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /home/her/buttercup_dir -- \</KBD>
<DD><KBD>&nbsp;&nbsp; -extract /sounds /home/her/sounds_from_me</KBD></DD>
</DD>
<DT>Consider to enter dialog mode and use commands like
<KBD>-cd , -du , -lsl , -find<KBD>.

Very special thanks to Andy Polyakov whose
