ISOINFO(8) ISOINFO(8)
NAME
isoinfo, isovfy, inodump - Utility programs for dumping
and verifying iso9660 images.
SYNOPSIS
isodump isoimage
isoinfo [ -R ] [ -f ] [ -l ] [ -T ] [ -N ] [ -i isoimage ]
[ -x path ]
isovfy isoimage
DESCRIPTION
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 arbi-
trary 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' com-
mand exits 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:
-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.
-R
Extract information from Rock Ridge extensions (if
present) for permissions, file names and owner-
ships.
-J
Use Joliet directory records in addition to
regular iso9660 file names. This is primarily use-
ful when the discs are to be used on Windows-NT or
Windows-95 machines. The Joliet filenames are
specified in Unicode and each path component can be
up to 64 Unicode characters long.
-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 dis-
play.
-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 software is not beta.
