Ubuntu Manpage: devdump, isoinfo, isovfy, isodump - Utility programs for dumping and verifying iso9660

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 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:@ .

On Linux, drives connected to a parallel port adapter are mapped to a virtual SCSI
bus. Different adapters are mapped to different targets on this virtual SCSI bus.

If no dev option is present, the program will try to get the device from the
CDR_DEVICE environment.

If the argument to the dev= option does not contain the characters ',', '/', '@' or
':', it is interpreted as an label name that may be found in the file
/etc/wodim.conf (see FILES section).

The options -i and dev=target are mutual exclusive.

-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.

       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 definitely found a bug, send a mail to this list or to

BUGS

       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.

              Note that this forces the program to create  a  pipe  to  the  rsh(1)  program  and
              disallows  the  program to directly access the network socket to the remote server.
              This makes it impossible to set  up  performance  parameters  and  slows  down  the
              connection compared to a root initiated rcmd(3) 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 ':'.

Each line that follows a label contains a TAB separated list of items.
Currently, four items are recognized: the SCSI ID of the drive, the default
speed that should be used for this drive, the default FIFO size that should
be used for this drive and drive specific options. The values for speed and
fifosize may be set to -1 to tell the program to use the global defaults.
The value for driveropts may be set to "" if no driveropts are used. A
typical line may look this way:

teac1= 0,5,0 4 8m ""

yamaha= 1,6,0 -1 -1 burnfree

This tells the program that a drive named teac1 is at scsibus 0, target 5,
lun 0 and should be used with speed 4 and a FIFO size of 8 MB. A second
drive may be found at scsibus 1, target 6, lun 0 and uses the default speed
and the default FIFO size.
