LOGIN(1) UNIX Programmer's Manual LOGIN(1)

NAME

    login  -  sign on

SYNOPSIS

    login [ username ]

DESCRIPTION

    The _l_o_g_i_n 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 _l_o_g_i_n 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 ._m_a_i_l and message-
    of-the-day files.  _L_o_g_i_n initializes the user and group IDs
    and the working directory, then executes a command inter-
    preter (usually _s_h(1)) according to specifications found in
    a password file.  Argument 0 of the command interpreter is
    `-sh.

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