NAME
login - sign on
SYNOPSIS
/etc/login name
/etc/login -f name
/etc/login -p passwd-line
DESCRIPTION
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 speci‐
fications 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.
