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 isoimageDESCRIPTION¶
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 genisoimage. It isn't all that clear how useful this is
anymore, but it doesn't hurt to have this around.
OPTIONS¶
The options common to all programs are -help,-h,-version, i=name,dev=name. The isoinfo program has additional command line options. The options are:- -help
- -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, Joliet extensions and Eltorito boot information 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. The options -i and dev=target are mutual exclusive.
- dev=target
- Sets the SCSI target for the drive, see notes above. A
typical device specification is dev=6,0 . If a filename must
be provided together with the numerical target specification, the filename
is implementation specific. The correct filename in this case can be found
in the system specific manuals of the target operating system. On a
FreeBSD system without CAM support, you need to use the
control device (e.g. /dev/rcd0.ctl). A correct device specification
in this case may be dev=/dev/rcd0.ctl:@ .
- -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 genisoimage(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¶
The author of the original sources (1993 ... 1998) is Eric Youngdale <ericy@gnu.ai.mit.edu> or <eric@andante.jic.com> is to blame for these shoddy hacks. Joerg Schilling wrote the SCSI transport library and its adaptation layer to the programs and newer parts (starting from 1999) of the utilities, this makes them Copyright (C) 1999-2004 Joerg Schilling. Patches to improve general usability would be gladly accepted. This manpage describes the program implementation of isoinfo as shipped by the cdrkit distribution. See http://alioth.debian.org/projects/debburn/ for details. It is a spinoff from the original program distributed in the cdrtools package [1]. However, the cdrtools developers are not involved in the development of this spinoff and therefore shall not be made responsible for any problem caused by it. Do not try to get support for this program by contacting the original author(s). If you have support questions, send them to debburn-devel@lists.alioth.debian.orgBUGS¶
The user interface really sucks.FUTURE IMPROVEMENTS¶
These utilities are really quick hacks, which are very useful for debugging problems in genisoimage 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 cdrkit package, and the primary download site is http://debburn.alioth.debian.org/ and FTP mirrors of distributions. Despite the name, the software is not beta.ENVIRONMENT¶
- CDR_DEVICE
- This may either hold a device identifier that is suitable to the open call of the SCSI transport library or a label in the file /etc/wodim.conf.
- RSH
- If the RSH environment is present, the remote
connection will not be created via rcmd(3) but by calling the
program pointed to by RSH. Use e.g. RSH=/usr/bin/ssh to
create a secure shell connection.
- RSCSI
- If the RSCSI environment is present, the remote SCSI
server will not be the program /opt/schily/sbin/rscsi but the
program pointed to by RSCSI. Note that the remote SCSI server
program name will be ignored if you log in using an account that has been
created with a remote SCSI server program as login shell.
FILES¶
- /etc/wodim.conf
- Default values can be set for the following options in /etc/wodim.conf.
- CDR_DEVICE
- This may either hold a device identifier that is suitable to the open call of the SCSI transport library or a label in the file /etc/wodim.conf that allows to identify a specific drive on the system.
- Any other label
- is an identifier for a specific drive on the system. Such
an identifier may not contain the characters ',', '/', '@' or ':'.
