       mount, umount - mount or unmount file systems

       /etc/mount [ options ] [ device ] [ directory ]

       /etc/umount [ options ] [ device ] [ directory ]

       This  is a general description of the command.  Additional descriptions
       are provided to define the syntax and options for the NFS and UFS  file

       Each invocation of the command announces to the system that a file sys‐
       tem is present on the device device.  The file system may be  local  or
       remote.	File directory must exist as a directory file.	It becomes the
       name of the newly mounted file system root.

       If invoked without arguments, prints the list of mounted file systems.

       Physically write-protected disks and magnetic tape file systems must be
       mounted read-only or an error will occur at mount time.

       General	users  can  only mount file systems with certain restrictions.
       For example, the user, other than the superuser, performing  the	 mount
       must own the directory directory.  Furthermore, no users other than the
       superuser can execute or programs on  the  mounted  file	 systems.   In
       addition, users other than the superuser cannot access block or special
       character devices such as on the mounted file systems.

       The command announces to the system that the removable file system pre‐
       viously	mounted on the specified directory is to be removed.  Only the
       person who mounted a  particular	 file  system  or  the	superuser  can
       unmount the file system again.

       -a	   Reads  the  file  and mounts, or unmounts, all file systems
		   listed there.

       -f	   Fast unmount.  The option has no  meaning  for  local  file
		   systems  and	 directories.  However, for remote file system
		   types (such as  NFS),  the  option  causes  the  client  to
		   unmount  the	 remotely mounted file systems and directories
		   without notifying the server.  This can avoid the delay  of
		   waiting for acknowledgment from a server that is down.

       -o options  Specifies a string that is passed to the kernel and used by
		   the specific file system's mount  routine  in  the  kernel.
		   For	specific  options,  refer  to the file system-specific
		   description, such as

       -r	   Indicates that the file system is to be mounted read	 only.
		   To  share a disk, each host must mount the file system with
		   the -r option.

       -t type	   Specifies the type of file system is being  mounted.	  When
		   used with the option, the option mounts all file systems of
		   the given type found in the file.  For specific file system
		   types,  refer to the file system-specific description, such

       -v	   Tells what did or did not happen.  (Verbose flag)

       The options for are:

       -a	   Unmounts all mounted file systems.  It may be necessary  to
		   execute  twice to accomplish unmounting of all mounted file

       -v	   Tells what did or did not happen.  (Verbose flag)

       Mounting corrupted file systems will crash the system.
