LOGIN(8)                                                 LOGIN(8)

          login - sign on

          /etc/login name
          /etc/login -f name
          /etc/login -p passwd-line

          Login is executed by getty(8). See `How to Get Started' for
          how to dial up initially.

          Login asks for a password if appropriate.  Echoing is turned
          off during the typing of the password.  The -f option forces
          login of the named user, without a password.  -p is similar
          to -f but uses the supplied line of the password file
          instead of the appropriate one in /etc/passwd. Both of these
          options will demand a typed password if the named user is
          the super-user.

          After a successful login, accounting files are updated, the
          message of the day is printed, and the user is informed of
          the existence of mail. Login initializes the user and group
          IDs and the working directory, then executes a command
          interpreter (usually sh(1)) according to specifications
          found in /etc/passwd. Argument 0 of the command interpreter
          is the name of the command interpreter with a leading dash
          (`-') prepended.

          Login also initializes the environment with information
          specifying home directory, search path, and an indication of
          the source of the login if appropriate.

          Only the super-user may execute login.

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

          init(8), newgrp(1), getty(8), su(8), passwd(1)
