[Bradford] Intro to the command line

[hudsonjr at ntlworld.com]

Steve's mentioned a couple I use.

Whether this is the easiest way to do things, I don't know but I make regular use of the up arrow to get back through the command history.

Also rather than clearing the whole history, I edit .bash_history to delete everything except a number of strings which I use regularly.

I also make frequent use of locate to find files.
