.cshrc

This file is run every time you start up a cshell while working. The .cshrc file sets many of the variables that determine how the UNIX environment behaves. The .cshrc file is located in your home directory. To see it, enter your home directory, and type 'ls -a', for a listing of all files in the directory. To view it's contents, type 'more .cshrc'. This example is fully commented and explains what each command does.

.login

This program executes its commands upon login, but is dormant after the first execution. The commands added in here should be ones needed at login, but not in every instance of a shell, such as terminal settings, mail checks, etc.
