Overview
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 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 explicitly stating a version number.
-
-G group -
Set the group of the files in the file system to group. The default gid on volumes without extended attributes or Rockridge extensions 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
-oflag 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-

-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_cd9660will 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 theinfocommand 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
