LOGIN(1) Cygwin Manual LOGIN(1)NAMElogin - sign on
SYNOPSISlogin [ name ]
login-p
login-h hostname
login-f name
DESCRIPTIONlogin 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 vari‐
ables 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 speci‐
fied 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.
