       mount, umount - mount and unmount file systems

SYNOPSIS

       FStype]

       FStype] specific_options] {special|directory}

       FStype] specific_options] special directory

       {special|directory}

       FStype] host]

DESCRIPTION

       The command mounts file systems.  Only a superuser can mount file systems.  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 supported.  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 neces-
			     sarily 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 statis-
			     tics 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-spe-
			     cific  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 supported.  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 regardless of activity on the file system.  Not supported by all file system
			     types.  See file system type specific man pages for more information.  If the file system type man page does not men-
			     tion 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 special 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 verify the command line.

EXAMPLES

       List the file systems currently mounted:

       Mount the HFS file system at directory

       Unmount the same file system:

WARNINGS

       If  you receive a message that says "Can't send after socket shutdown", contact your system administrator to make sure the is running prop-
       erly.
