The .tcshrc (pronounced dot-t-c-s-h-r-c) file tells the shell (assuming you are using the tcsh shell environment all) sorts of setup parameters, most important of which are where to find certain programs. For some unknown reason, new accounts are not setup with any such file so we provide the following as a good starting point.
Directions: Click on the following link to download the tcshrc file. Then save it in your home directory as .tcshrc (don't forget the dot in front). (I.e. save it as ~/.tcshrc)
Finally, log out and log back in again.
