mount_cd9660 -- mount an ISO-9660 file system
mount_cd9660 [-begjrv] [-o options] [-s startsector] [-C charset] special
| node
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.
-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.
The following command can be used to mount a Kodak Photo-CD:
mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom
cdcontrol(1), mount(2), unmount(2), fstab(5), mount(8)
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.
The mount_cd9660 utility first appeared in 4.4BSD.
The unicode conversion routine was added by Ryuichiro Imura
<[email protected]> at 2003.
