.login is a Unix shell script which is executed for a user every time that user logs in.
A standard .login file will set important environment variables such as $PATH and may also run commands, such as `fortune`.
The .login file will be stored in the users home directory.
.login is used by the C and TCSH shells. The Bourne, Korn, and Bash shells use a startup file called .profile instead.
The C and TCSH shells also use a startup file called .cshrc.
Also, the /etc/.login shared startup file will by executed by all C and TSCH shells.
