OK - I'll admit that this is quite a trivial use of the "alias" command which (if your running the default 'bash' shell) lets you rename commands - replacing longer names with shorter ones, and adding in some default options too. Here's an example of that, where I am adding the -F option to all my ls commands, as I would like a trailing @ * or / to indicate a link, executable or directory on my listing:

alias commands remain active only for the life of the current shell - type them in at the command line, and they'll not be transferred to any new windows. And you'll loose them completely when you log out or close the window in which you have set them. If you want to make them permanent, edit them into your .bashrc file - that's the file that's read every time you start a new shell.

oh .. ".bashrc" => "Bourne Again Shell Runtime Commands" if you wondered!
