# umount(1)

    NAME
         umount - unmount a mounted file system

    SYNOPSIS
         umount special

    EXAMPLES

         umount /dev/fd1     # Unmount diskette 1

    DESCRIPTION

         A mounted file system is unmounted after the cache has  been  flushed  to
         disk.   A  diskette should never be removed while it is mounted.  If this
         happens, and is discovered  before  another  diskette  is  inserted,  the
         original  one  can  be replaced without harm.  Attempts to unmount a file
         system holding working directories or open files will be rejected with  a
         'device busy' message.
