NAME    [Toc]    [Back]

     mount_cd9660 -- mount an ISO-9660 file system

SYNOPSIS    [Toc]    [Back]

     mount_cd9660 [-begjrv] [-o options] [-s startsector] [-C charset] special
		  | node

DESCRIPTION    [Toc]    [Back]

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

     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
	     explicitly stating a version number.

     -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.
	     nostrictjoliet  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 system 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    [Toc]    [Back]

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

	   mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom

SEE ALSO    [Toc]    [Back]

     cdcontrol(1), mount(2), unmount(2), fstab(5), mount(8)

BUGS    [Toc]    [Back]

     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 don't 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.

HISTORY    [Toc]    [Back]

     The mount_cd9660 utility first appeared in 4.4BSD.

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