<H2>ISO 9660 Rock Ridge Filesystem Manipulator for Linux</H2>
</CENTER>

<P>
<H2>Purpose:</H2>
xorriso 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.

<H2>Command Examples:</H2>
<DL>
<DT>Get an overview of drives and their addresses</DT>
<DD>#<KBD>&nbsp;xorriso -devices</KBD></DD>
<DT>Being superuser avoids permission problems with /dev/srN resp. /dev/hdX .
</DT>
<DT>Ordinary users should then get granted rw access to the /dev files
as listed by option -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>

<HR>

<DT>Get info about a particular drive and loaded media:</DT>
<DD>$<KBD>&nbsp;xorriso -indev /dev/sr0 -du / -- -toc 2>&amp;1 | less</KBD></DD>

<DT>Make re-usable media writable again, delete any ISO 9660 image:</DT>
<DD>$<KBD>&nbsp;xorriso -outdev /dev/sr0 -blank fast -eject all</KBD></DD>

write it to media and immediately eject media without
previously reloading the written image.

Touch / in order to mark the image as worth to be written.
<BR>

<DT>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.</DT>

<DD><KBD>enter option and arguments :</KBD></DD>

</DT>

<DT>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. On CD-R[W], DVD-R[W] and DVD+R
older states can be retrieved by help of mount option "session=".
So this constitutes true incremental backup.
On overwriteable media only the newest state is accessible.

<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.</DT>

Many thanks to Derek Foreman and Ben Jansens for starting libburn.
<BR>
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 overwriteable media.
