Debugging .cshrc

  1. Move your .cshrc so bad edits won’t ruin things: mv /.cshrc ./test_cshrc
  2. Edit ./test_cshrc until you think it is correct (don’t log out until you’re certain it works!)
  3. Open a new terminal and SSH into any system
  4. Give your terminal the settings in your test_cshrc: source ./test_cshrc
  5. Repeat 2 to 4
  6. Once you think you have it:
  • While keeping a couple of terminals open for safety: cp ./test_cshrc .cshrc
  • Confirm there are no errors by SSH’ing into any system
  1. While still keeping a couple of terminals open, confirm your .cshrc works by trying to login via an X window system on a different computer
