.cshrc
     
         (C Shell run commands) A {C Shell} startup
        configuration file.  This file is found in a user's {home
        directory} and can contain shell and other commands to set
        variables, define aliases, and perform any other
        initialisation which should happen for every shell (as opposed
        to {.login} which is only run for a {login shell}).
     
        Compare {AUTOEXEC.BAT} on {MS-DOS}.
     
        See also {rc}.
