Setting shell variables

To define a temporary value to a shell variable use the command:

   set variable_name=value

The value of this variable will remain set until you exit from this shell. The value of this variable is not exported to other C shells when they are invoked.

To give a lasting value to a shell variable:

1. Use an editor to open your .cshrc (.tcshrc) file and add the line:

   set variable_name=value

2. Save the file and leave the editor.

3. Enter the command:

   source .cshrc

This adds the value of the shell variable to your shell's present environment. When other C shells are invoked they will also have this variable set.
