mount_cd9660(8)

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 format

ted 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 sepa

rated 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 cor

rect
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/cd0c /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.
