screen: Lock
8.3 Lock
========
-- Command: lockscreen
('C-a x', 'C-a C-x')
Call a screenlock program. Screen does not accept any command keys
until this program terminates. Meanwhile processes in the windows
may continue, as the windows are in the detached state. The
screenlock program may be changed through the environment variable
'$LOCKPRG' (which must be set in the shell from which 'screen' is
started) and is executed with the user's uid and gid.
Warning: When you leave other shells unlocked and have no password
set on 'screen', the lock is void: One could easily re-attach from
an unlocked shell. This feature should rather be called
'lockterminal'.
