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 in-
     formed of the existence of .mail and message-of-the-day files.  Login  ini-
     tializes  the user and group IDs and the working directory, then executes 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 program-
     ming counselor.
