      /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]

      /usr/sbin/umount -a [-F FStype] [-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.  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.








 Hewlett-Packard Company            - 1 -    HP-UX Release 10.20:  July 1996












 mount(1M)                                                         mount(1M)








           -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.


           -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.
