== NAME ==<br />
login - sign on<br />
<br />
== SYNOPSIS ==<br />
login [ username ]<br />
<br />
== DESCRIPTION ==<br />
The _l_o_g_i_n command is used when a user initially signs on, or<br />
it may be used at any time to change from one user to<br />
another. The latter case is the one summarized above and<br />
described here. See `How to Get Started' for how to dial up<br />
initially.<br />
<br />
If _l_o_g_i_n is invoked without an argument, it asks for a user<br />
name, and, if appropriate, a password. Echoing is turned<br />
off (if possible) during the typing of the password, so it<br />
will not appear on the written record of the session.<br />
<br />
After a successful login, accounting files are updated and<br />
the user is informed of the existence of ._m_a_i_l and message-<br />
of-the-day files. _L_o_g_i_n initializes the user and group IDs<br />
and the working directory, then executes a command inter-<br />
preter (usually _s_h(1)) according to specifications found in<br />
a password file. Argument 0 of the command interpreter is<br />
`-sh.<br />
<br />
Login is recognized by _s_h(1) and executed directly (without<br />
forking).<br />
<br />
== FILES ==<br />
/etc/utmp accounting<br />
/usr/adm/wtmp accounting<br />
/usr/spool/mail/* mail<br />
/etc/motd message-of-the-day<br />
/etc/passwd password file<br />
<br />

<br />
== DIAGNOSTICS ==<br />
`Login incorrect,' if the name or the password is bad.<br />
`No Shell', `cannot open password file', `no directory':<br />
consult a programming counselor.<br />
