| If someone comes up to your terminal and types "login name" you
| will be logged out and he will be logged in. If his login process
| "finishes" i.e. he logs out, the system will display a login 
| banner. YOU WILL BE GONE! I'd say whoever did this when you were

| login with su???

Nope.  Typing

% login me

logs out the current user.  What the original message said was:

% (login me)

which forces login to run in a subshell.  I often pull that trick with
newgrp, we lacking sg.
