DESCRIPTION
The command mounts file systems. Only a superuser can mount file sys‐
tems. Other users can use to list mounted file systems.
The 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, attempts to determine the missing value from
an entry in the file. can be invoked on any removable file system,
except
If is invoked without any arguments, it lists all of the mounted file
systems from the file system mount table,
The command unmounts mounted file systems. Only a superuser can
unmount file systems.
Options (mount)
The command recognizes the following options:
Attempt to mount all file systems described in
All optional fields in must be included and sup‐
ported. If the option is specified, all file
systems in with that FStype are mounted. If is
specified in an entry's option list, this entry
is skipped. File systems are not necessarily
mounted in the order listed in
Verbose mode. Write a message to the standard output indicating
which file system is being mounted.
Specify FStype, the file system type on which to operate.
See fstyp(1M). If this option is not included on
the command line, then it is determined from
either by matching special with an entry in that
file, or from file system statistics of special,
obtained by (see statfsdev(3C)).
Unmount only those file systems listed in
that are remote-mounted from host.
Limit actions to local file systems only.
Specify options specific to each file system type.
specific_options is a list of comma separated
suboptions and/or keyword/attribute pairs
intended for a FStype-specific version of the
command. See the FStype-specific manual entries
for a description of the specific_options sup‐
ported, if any.
Report the list of mounted file systems in the
format.
Prevent the display of error messages
that result from an attempt to mount already
mounted file systems.
Mount the specified file system as read-only.
Physically write-protected file systems must be
mounted in this way or errors occur when access
times are updated, whether or not any explicit
write is attempted.
Report the regular output with file system type and flags;
however, the directory and special fields are
reversed.
Echo the completed command line,
but perform no other action. The command line is
generated by incorporating the user-specified
options and other information derived from This
option allows the user to verify the command
line.
Options (umount)
The command recognizes the following options:
Attempt to unmount all file systems described in
All optional fields in must be included and sup‐
ported. If FStype is specified, all file systems
in with that FStype are unmounted. File systems
are not necessarily unmounted in the order listed
in
Forced unmount.
A forced unmount is one which will occur regard‐
less of activity on the file system. Not sup‐
ported by all file system types. See file system
type specific man pages for more information. If
the file system type man page does not mention
forced unmount, then it is not supported for that
file system type.
Specify FStype, the file system type on which to operate.
If this option is not included on the command
line, then it is determined from by matching spe‐
cial with an entry in that file. If no match is
found, the command fails.
Verbose mode. Write a message to standard output indicating
which file system is being unmounted.
Echo the completed command line, but perform no other action.
The command line is generated by incorporating
the user-specified options and other information
derived from This option allows the user to ver‐
ify the command line.
EXAMPLES
List the file systems currently mounted:
Mount the HFS file system at directory
Unmount the same file system:
