/usr/sbin/umount [-v] [-V] {special|directory}
DESCRIPTION [Toc] [Back]
The mount command mounts file systems. Only a superuser can mount
file systems. Other users can use mount to list mounted file systems.
The mount command attaches special, a removable file system, to
directory, a directory on the file tree. directory, which must
already exist, will become the name of the root of the newly mounted
file system. special and directory must be given as absolute path
names. If either special or directory is omitted, mount attempts to
determine the missing value from an entry in the /etc/fstab file.
mount can be invoked on any removable file system, except /.
If mount is invoked without any arguments, it lists all of the mounted
file systems from the file system mount table, /etc/mnttab.
The umount command unmounts mounted file systems. Only a superuser
can unmount file systems.
Options (mount) [Toc] [Back]
mount recognizes the following options:
-a Attempt to mount all file systems described in
/etc/fstab. All optional fields in /etc/fstab must
be included and supported. If -F cdfs is specified,
all CDFS file systems in /etc/fstab are mounted. If
noauto is specified in an entry's option list, this
entry is skipped. File systems are not necessarily
mounted in the order listed in /etc/fstab.
-e Verbose mode. Write a message to standard output
indicating which file system is being mounted.

-F cdfs Specify the CDFS file system type (see fstyp(1M)).
-l Limit actions to local file systems only.
-o specific_options
Specify options specific to the CDFS file system
type. specific_options is a list of comma separated
suboptions and/or keyword/attribute pairs intended
for the CDFS specific module of the command.
The following specific_options are valid on CDFS file
systems.
cdcase Suppress the display of version numbers.
Show and match file names as lower case.
rr Use Rock Ridge extension to the ISO-9660
file system (default).
norr Do not use Rock Ridge extension to the
ISO-9660 file system.
defaults Use all default options. When given,
this must be the only option specified.
ro Mount read-only (default).
suid Allow set-user-ID execution (default).
nosuid Do not allow set-user-ID execution.
-p Report the list of mounted file systems in the
/etc/fstab format.
-Q Prevent the display of error messages resulting from
an attempt to mount already mounted file systems.
-r Mount the specified file system as read-only. This
option is equivalent to the -o ro specific_option.
For CDFS file systems this is a default option.
-v Report the regular output with file system type and
flags; however, directory and special fields are
reversed.
-V Echo the completed command line, but performs no
other action. The command line is generated by
incorporating the user-specified options and other
information derived from /etc/fstab. This option
allows the user to verify the command line.

Options (umount) [Toc] [Back]
umount recognizes the following options:
-a Attempt to unmount all file systems described in
/etc/mnttab. All optional fields in /etc/mnttab must
be included and supported. If -F cdfs is specified,
all CDFS file systems in /etc/mnttab are unmounted.
File systems are not necessarily unmounted in the
order listed in /etc/mnttab.
-F cdfs Specify the CDFS file system type (see fstyp(1M)).
-v Verbose mode. Write a message to standard output
indicating which file system is being unmounted.
-V Echo the completed command line, but performs no
other action. The command line is generated by
incorporating the user-specified options and other
information derived from /etc/fstab. This option
allows the user to verify the command line.
DIAGNOSTICS [Toc] [Back]
umount complains if the special file is not mounted or if it is busy.
The file system is busy if it contains an open file or some logged-in
user's working directory.
EXAMPLES [Toc] [Back]
Mount a local CDFS disk:
mount -F cdfs /dev/dsk/c0t0d4 /cdrom
Unmount a local CDFS disk:
umount /dev/dsk/c0t0d4
WARNINGS [Toc] [Back]
Some degree of validation is done on the file system, however, it is
generally unwise to mount file systems that are defective, corrupt, or
of unknown origin.
NOTES [Toc] [Back]
Additional CD-ROM formats are supported using PFS (Portable File
System) utilities. See pfs(4) for more details.
