Problem:
Working on the command line on the Leland AFS space is primitive. By using the bash shell and a few tweaks, the usability of the command line greatly improves.
Solution
Step 1: Edit the bashrc file. vim ~/.bashrc. You can use pico or any of your favorite editors.
Step 2: Paste the text below into the ~/.bashrc file. Copy the text below. In VI type "i" for insert mode and then ctrl-insert to paste.
Step 3: Save and quit the file. In VI type :wq
Now type "bash" to load your new bash shell. If you copied and pasted correctly, you should see your prompt change into a green and purple color.
Remember each time you log into the command line, you will need to type "bash" to load the bash Shell.
