1.5) First Commands

I would like you to try the following commands:

ls - lists the contents of the directory

clear - clears the page and returns the prompt to the top of the terminal

Almost everything you do in Unix will involve a file involving data or text that is in a file and so we need to learn how to make a file or data file before we go any further.

The first few pages in the next section will teach you how to use an editor. If you are already know how to edit files, you can skip ahead.
