NAME
       login  -	 sign on

SYNOPSIS
       login [ username	]

DESCRIPTION
       The  login command is used when a user initially	signs on, or it	may be
       used at any time	to change from one user	to another.  The  latter  case
       is  the	one  summarized	 above	and  described	here.  See `How	to Get
       Started'	for how	to dial	up initially.

       If login	is invoked without an argument,	it asks	for a user name,  and,
       if appropriate, a password.  Echoing is turned off (if possible)	during
       the typing of the password, so it will not appear on the	written	record
       of the session.

       After  a	successful login, accounting files are updated and the user is
       informed	of the existence of .mail and message-of-the-day files.	 Login
       initializes the user and	group IDs and the working directory, then exe-
       cutes a command interpreter (usually sh(1)) according to	specifications
       found  in  a  password  file.  Argument 0 of the	command	interpreter is
       `-sh.

       Login is	recognized by sh(1) and	executed directly (without forking).

FILES
       /etc/utmp      accounting
       /usr/adm/wtmp  accounting
       /usr/mail/*    mail
       /etc/motd      message-of-the-day
       /etc/passwd    password file

SEE ALSO
       init(8),	newgrp(1), getty(8), mail(1), passwd(1), passwd(5)

DIAGNOSTICS
       `Login incorrect,' if the name or the password is bad.
       `No Shell', `cannot open	password file',	`no directory':	consult	a pro-
       gramming	counselor.
