LOGIN(1)

NAME
login - sign on

SYNOPSIS
login [ name ]
login -p
login -h hostname
login -f name

DESCRIPTION
login is used when signing onto a system. If an argument is not given, login prompts for the username. If the file /etc/nologin exists, the content of the file is written to stdout and nobody is permitted to log into the system. Random administrative things, such as setting the UID and GID of the tty are performed. The TERM environment variable is preserved, if it exists (other environment variables are preserved if the -p option is used). Then the HOME, PATH, SHELL, MAIL, and LOGNAME environment variables are set. PATH is not changed from the system PATH if it's found. Otherwise PATH defaults to /usr/local/bin:/bin:/usr/bin. Authentication is done via SAM database on NT/W2K systems and via 56 bit DES passwords in /etc/passwd, on W9X systems. The user's shell is then started. If no shell is specified for the user in /etc/passwd, then /bin/sh is used. If there is no directory specified in /etc/passwd, then / is used (the home directory is checked for the .hushlogin file described above).

OPTIONS

-p  Used by getty(8) to tell login not to destroy the environment. This is disabled in the Cygwin version.

-f  Used to skip a second login authentication. This specifically does not work for root.

-h  Used by other servers (i.e., telnetd(8)) to pass the name of the remote host to login so that it may be placed in utmp and wtmp.

FILES
/var/run/utmp
/var/log/wtmp
