RedHat 9 (Linux i386) - man page for isoinfo (redhat section 8)

ISOINFO(8)									       ISOINFO(8)

NAME
       devdump,  isoinfo,  isovfy,  isodump  - Utility programs for dumping and verifying iso9660
       images.

SYNOPSIS
       devdump isoimage

       isodump isoimage

       isoinfo [ -d ] [ -h ] [ -R ] [ -J ] [ -j charset ] [ -f ] [ -l ] [ -p ] [ -T sector ] [ -N
       sector ] [ -i isoimage ] [ -x path ]

       isovfy isoimage

DESCRIPTION
       devdump	is  a crude utility to interactively display the contents of device or filesystem
       images.	The initial screen is a display of the first 256 bytes of  the	first  2048  byte
       sector.	The commands are the same as with isodump.

       isodump	is  a  crude  utility  to interactively display the contents of iso9660 images in
       order to verify directory integrity.  The initial screen is a display of the first part of
       the root directory, and the prompt shows you the extent number and offset in the extent.

	      You  can	use  the  'a'  and 'b' commands to move backwards and forwards within the
	      image. The 'g' command allows you to goto an arbitrary extent, and the 'f'  command
	      specifies a search string to be used. The '+' command searches forward for the next
	      instance of the search string, and the 'q' command exits devdump or isodump.

       isoinfo is a utility to perform directory like listings of iso9660 images.

       isovfy is a utility to verify the integrity of an iso9660 image.  Most  of  the	tests  in
       isovfy  were  added after bugs were discovered in early versions of mkisofs.  It isn't all
       that clear how useful this is anymore, but it doesn't hurt to have this around.

OPTIONS
       Only the isoinfo program has any command line options. These are:

       -h     print a summary of all options.

       -d     Print information from the primary volume descriptor (PVD) of  the  iso9660  image.
	      This includes information about Rock Ridge and Joliet extensions if present.

       -f     generate	output as if a 'find . -print' command had been run on the iso9660 image.
	      You should not use the -l image with the -f option.

       -i iso_image
	      Specifies the path of the iso9660 image that we wish to examine.

       -l     generate output as if a 'ls -lR' command had been run on the  iso9660  image.   You
	      should not use the -f image with the -l option.

       -N sector
	      Quick  hack  to  help examine single session disc files that are to be written to a
	      multi-session disc. The sector number specified is the sector number at  which  the
	      iso9660  image should be written when send to the cd-writer. Not used for the first
	      session on the disc.

       -p     Print path table information.

       -R     Extract information from Rock Ridge extensions (if present) for  permissions,  file
	      names and ownerships.

       -J     Extract information from Joliet extensions (if present) for file names.

       -j charset
	      Convert  Joliet file names (if present) to the supplied charset. See mkisofs(8) for
	      details.

       -T sector
	      Quick hack to help examine multi-session images that have already been burned to	a
	      multi-session  disc. The sector number specified is the sector number for the start
	      of the session we wish to display.

       -x pathname
	      Extract specified file to stdout.

AUTHOR
       Eric Youngdale <ericy@gnu.ai.mit.edu> or <eric@andante.jic.com>	is  to	blame  for  these
       shoddy hacks. Patches to improve general usability would be gladly accepted.

BUGS
       The user interface really sucks.

FUTURE IMPROVEMENTS
       These  utilities  are  really quick hacks, which are very useful for debugging problems in
       mkisofs or in an iso9660 filesystem. In the long run, it would be nice to  have	a  daemon
       that would NFS export a iso9660 image.

       The isoinfo program is probably the program that is of the most use to the general user.

AVAILABILITY
       These  utilities come with the mkisofs package, and the primary ftp site is tsx-11.mit.edu
       in /pub/linux/BETA/cdrom/mkisofs and many other mirror sites. Despite the name, the  soft-
       ware is not beta.
