Same as the
logincommand except that the default setting for new windows is changed. This defaults to `on' unless otherwise specified at compile time (see Installation). Both commands are only present when
screenhas been compiled with utmp support.
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 onand
bind O login offwill map these keys to be C-a I and C-a O (see Key Binding).
