MOUNT_CD9660(8) 	     System Manager's Manual		 MOUNT_CD9660(8)

NAME
     mount_cd9660 -- mount an ISO-9660 file system

SYNOPSIS
     mount_cd9660 [-begjrv] [-C charset] [-G gid] [-m mask] [-M mask]
		  [-o options] [-s startsector] [-U uid] special node

DESCRIPTION
     The  mount_cd9660 utility attaches the ISO-9660 file system residing on the
     device special to the global file system namespace at  the  location  indi-
     cated by node.  This command is normally executed by mount(8) at boot time.

     The options are as follows:

     -b      Relax  checking  for  Supplementary  Volume  Descriptor Flags field
	     which is set to a wrong value on some Joliet formatted disks.

     -e      Enable the use of extended attributes.

     -g      Do not strip version numbers on files.  (By default, if  there  are
	     files with different version numbers on the disk, only the last one
	     will  be  listed.)  In either case, files may be opened without ex-
	     plicitly stating a version number.

     -G group
	     Set the group of the files in the file system to  group.	The  de-
	     fault  gid  on volumes without extended attributes or Rockridge ex-
	     tensions is zero.

     -U user
	     Set the owner of the files in the file system to user.  The default
	     uid on volumes without extended attributes or Rockridge  extensions
	     is zero.

     -m mask
	     Specify  the maximum file permissions for files in the file system.
	     For example, a mask of 544 limits the owner  to  read  and  execute
	     permissions  for  files  and  others  to only read permission.  See
	     chmod(1) for more information about octal file modes.  The  default
	     mask  is 7777.  The default permissions on volumes without extended
	     attributes or Rockridge extensions is 555.

     -M mask
	     Specify the maximum file permissions for directories  in  the  file
	     system.  See the previous option's description for details.

     -j      Do not use any Joliet extensions included in the file system.

     -o      Options  are specified with a -o flag followed by a comma separated
	     string of options.  See the mount(8) man page for possible  options
	     and  their  meanings.   The  following  cd9660 specific options are
	     available:

	     extatt	   Same as -e.
	     gens	   Same as -g.
	     nojoliet	   Same as -j.
	     norrip	   Same as -r.
	     brokenjoliet  Same as -b.

     -r      Do not use any Rockridge extensions included in the file system.

     -s startsector
	     Start the file system at startsector.  Normally, if the  underlying
	     device  is  a CD-ROM drive, mount_cd9660 will try to figure out the
	     last track from the CD-ROM containing data, and start the file sys-
	     tem there.  If the device is not a CD-ROM, or the table of contents
	     cannot be examined, the file system will be started  at  sector  0.
	     This  option  can	be  used  to  override the behaviour.  Note that
	     startsector is measured in CD-ROM blocks,	with  2048  bytes  each.
	     This is the same as for example the info command of cdcontrol(1) is
	     printing.	It is possible to mount an arbitrary session of a multi-
	     session CD by specifying the correct startsector here.

     -C charset
	     Specify  local  charset  to  convert  Unicode file names when using
	     Joliet extensions.

     -v      Be verbose about the starting sector decisions made.

EXAMPLES
     The following command can be used to mount a Kodak Photo-CD:

	   mount_cd9660 -o rw -v -s 0 /dev/cd0 /cdrom

HISTORY
     The mount_cd9660 utility first appeared in 4.4BSD.

     The   Unicode   conversion   routine   was   added   by   Ryuichiro   Imura
     <imura@ryu16.org> in 2003.

BUGS
     POSIX device node mapping is currently not supported.

     Version numbers are not stripped if Rockridge extensions are  in  use.   In
     this case, accessing files that do not have Rockridge names without version
     numbers  gets  the  one with the lowest version number and not the one with
     the highest.

     There is no ECMA support.
