screen: Login
10.4 Login
==========
-- Command: deflogin state
(none)
Same as the 'login' command except that the default setting for new
windows is changed. This defaults to 'on' unless otherwise
specified at compile time (⇒Installation). Both commands
are only present when 'screen' has been compiled with utmp support.
-- Command: login [state]
('C-a L')
Adds or removes the entry in '/run/utmp' for the current window.
This controls whether or not the window is "logged in". In
addition to this toggle, it is convenient to have "log in" and "log
out" keys. For instance, 'bind I login on' and 'bind O login off'
will map these keys to be 'C-a I' and 'C-a O' (⇒Key
Binding).
