Screen User's Manual

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 (see section 26. 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 `/etc/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 (see section 14. Key Binding).
