Change the shell you are using

By default, your Unix shell is csh. What does this mean? Don't worry. But you want to change it to something more convenient to use.

1. Log in through SSH
2. At the prompt, type chsh <your username> /xhbin/tcsh

Now you can use up and down arrow keys to repeat previous commands.

You can also use the Tab key to complete partially typed filenames for you.
