Here is where you would want to put commands that make sense to be run one time at the beginning of your login, rather than every time you open another terminal window (which is what .cshrc is for).
Here are some possible contents of the file .login:
stty erase ^h kill ^u intr ^c
mesg y
biff n
set term = vt100
setenv DISPLAY ${hostname}:0
echo "Welcome dude"
There are manual pages for stty and
mesg and biff. Apart from the
personalized welcome message (echo...), these
commands inform the computer about terminal type,
keyboard configuration, display destination,
and whether to notify the user about incoming
messages/email.
