NAME
      mount, umount  - mount or unmount file systems and remote resources

SYNOPSIS
      mount [-v |-p]
      mount [-F FSType] [-V] [current_options] [-o specific_options] {special |
      mount_point}
      mount [-F FSType] [-V] [current_options] [-o specific_options] special
      mount_point
      umount [-V] [-o specific_options] {special | mount_point}

DESCRIPTION
      File systems other than root ( / ) are considered removable in the sense
      that they can be either available to users or unavailable.  mount
      notifies the system that special, a block special device or a remote
      resource, is available to users from the mount_point which  must already
      exist; it becomes the name of the root of the newly mounted special or
      resource.

      mount, when entered with arguments, validates all arguments  except for
      the device name and invokes an FSType specific mount module.  If invoked
      with no arguments, mount lists all the mounted file systems from the
      mount table.  If invoked with any of the following partial argument
      lists, for example, one of special or mount_point or when both arguments
      are specified but no  FSType is specified mount will search /etc/vfstab
      to fill in the missing arguments:  FSType, special, mount_point, and
      specific_options.  It will then invoke the FSType-specific mount module.

      Most FSTypes do not have a umount specific module. If one exists it is
      executed; otherwise the generic module unmounts the file systems.  If the
      -o option is specified the umount specific module is always executed.

      current_options are options supported by the s5-specific module of mount
      and umount.  Other FSTypes do not necessarily support these options.
      specific_options indicate suboptions specified in a comma-separated list
      of suboptions and/or keyword-attribute pairs for interpretation by the
      FSType-specific module of the command.

      The options are:

      -v        Print the output in a new style.  The new output has the FSType
                and flags displayed in addition to the old output.  The
                mount_point and special fields are reversed.

      -p        Print the list of mounted file systems in the /etc/vfstab
                format.

      -F        used to specify the FSType on which to operate. The FSType must
                be specified or must be determinable from /etc/vfstab while
                mounting a file system.  If FSType is not specified or if
                FSType does not exist in /etc/vfstab, FSType defaults to s5.

      -V        Echo the complete command line, but do not execute the command.
                The command line is generated by using the options and
                arguments provided by the user and adding to them information
                derived from /etc/vfstab.  This option should be used to verify
                and validate the command line.

      -o        used to specify FSType-specific options.

      mount can be used by any user to list mounted file systems and resources.
      Only a super-user can mount or unmount file systems.

NOTES
      mount does not prevent you from mounting a file system on a directory
      that's not empty.

      The old output format will be phased out in a future release and all
      output will be in the new -v format. The most significant changes are the
      addition of two new fields to show the FSType and flags and the reversal
      of the mount_point and special name.

      mount adds an entry to the mount table /etc/mnttab; umount removes an
      entry from the table.

FILES
      /etc/mnttab      mount table
      /etc/vfstab      list of default parameters for each file system.
