10.0;lo (log_off) *DM*, revision 1.0, 87/12/23
lo (log_off) log out from a node
usage: lo [-f] [-off] [-on]
DESCRIPTION
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, the command asks
you if you wish to blast the remaining processes (see -f below). Respond
either "y" or "n".
You can also disable the ability to log out. See -off below.
You can 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 filenames
(for example, 19l, color, none, and so on). 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, unless you specify
the -w option with cps or cpd.
OPTIONS
-f Force logout by blasting processes that cannot be stopped
normally. If you use this option, be aware that you may lose
some disk space. Use the salvager salvol to recover the disk
space. You may also lose files and programs that you had been
working with. Therefore, use the -f option as a last resort
when the normal logout procedure is not working.
-off Disable the ability to log out. When this option is specified,
the user who is currently logged in cannot log out.
-on Enable logout. Use this option to restore a user's ability to
log out.
