NAME¶
mount_cd9660 —
mount an ISO-9660 file
system
SYNOPSIS¶
mount_cd9660 |
[-begjrv]
[-C
charset]
[-o
options]
[-s
startsector] 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 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.
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.
