LO (LOG_OFF) -- Log off a node.
usage:  lo [-f] [-off] [-on]


FORMAT

  LO [options]


  The  LO  command  stops  all  user  processes (except those created by the CPS
  command and those created by the node startup file `NODE_DATA/STARTUP), closes
  all pads and files, and returns the display to the "Please log in:"  prompt.

  If  LO  cannot  terminate all active processes normally, then the command asks
  you whether or not you wish to blast the remaining processes (see  -F  below).
  Respond either "y" or "n".

  You may also disable the ability to log off.  See -OFF below.

  It  is  possible  to execute a DM command script automatically at logout.  The
  logout script must be in a file  named  `NODE_DATA/STARTUP_LOGOUT.type,  where
  'type'  is  one  of the standard display type extensions used for startup file
  names ('.19L', '.COLOR' or none). Note that you cannot start up new  processes
  with  CP,  CPS,  or  CPO  from this script because the DM is in the process of
  shutting down all existing processes.


OPTIONS

  -F                 Force log off by blasting processes that cannot be  stopped
                     normally.   If you use this option, be aware that some disk
                     space may be lost.  To recover  the  disk  space,  use  the
                     salvager  SALVOL.    Files  and  programs that you had been
                     working with may also be lost.  The -F option  should  only
                     be  used as a last resort when the normal logoff proceedure
                     is not working.

  -OFF               Disable the ability to  log  off.    When  this  option  is
                     specified,  the user who is currently logged in will not be
                     able to log off.

  -ON                Enable log off.  Use this option to restore the ability for
                     a user to log off.
