ISOINFO(1)									       ISOINFO(1)

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 specifica-
	      tion is dev=6,0 .  If a filename must be provided together with the numerical  tar-
	      get  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 dis-
       tribution. 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.org

       If you have definitely found a bug, send a mail to this list or to

       submit@bugs.debian.org

       writing at least a short description into the Subject and "Package: cdrkit" into the first
       line of the mail body.

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  dae-
       mon 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://deb-
       burn.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 disal-
	      lows  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.  Cur-
		     rently, 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 typ-
		     ical 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.
