 NAME
      mount, umount - mount and unmount file systems

 SYNOPSIS
      /usr/sbin/mount [-l] [-p|-v]

      /usr/sbin/mount -a [-F FStype] [-eQ]

      /usr/sbin/mount [-F FStype] [-eQrV] [-o specific_options]
	   {special|directory}

      /usr/sbin/mount [-F FStype] [-eQrV] [-o specific_options]
	   special directory

      /usr/sbin/umount [-v] [-V] {special|directory}

      /usr/sbin/umount -a [-F FStype] [-h host] [-v]

 DESCRIPTION
      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)
      The mount command 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 the -F option
			  is specified, all file systems in /etc/fstab with
			  that FStype 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 the standard
			  output indicating which file system is being
			  mounted.

	   -F FStype	  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 /etc/fstab, by matching
			  special with an entry in that file, or from file
			  system statistics of special, obtained by
			  statfsdev() (see statfsdev(3C)).

	   -l		  Limit actions to local file systems only.

	   -o specific_options
			  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 supported, if
			  any.

	   -p		  Report the list of mounted file systems in the
			  /etc/fstab format.

	   -Q		  Prevent the display of error messages that result
			  from an attempt to mount already mounted file
			  systems.

	   -r		  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.

	   -h		  Unmount only those file systems listed in
			  /etc/mnttab that are remote-mounted from host.

	   -v		  Report the regular output with file system type
			  and flags; however, the directory and special
			  fields are reversed.

	   -V		  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 /etc/fstab.	This option
			  allows the user to verify the command line.

    Options (umount)
      The umount command 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 FStype is

			  specified, all file systems in /etc/mnttab with
			  that FStype are unmounted.  File systems are not
			  necessarily unmounted in the order listed in
			  /etc/mnttab.

	   -F FStype	  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
			  /etc/mnttab by matching special with an entry in
			  that file.  If no match is found, the command
			  fails.

	   -v		  Verbose mode.	 Write a message to standard output
			  indicating which file system is being unmounted.

	   -V		  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 /etc/fstab.	This option
			  allows the user to verify the command line.

 EXAMPLES
      List the file systems currently mounted:

	   mount

      Mount the HFS file system /dev/dsk/c1t2d0 at directory /home:

	   mount -F hfs /dev/dsk/c1t2d0 /home

      Unmount the same file system:

	   umount /dev/dsk/c1t2d0
