1.4) Accessing Unix

A window (usually called a console or terminal) will now appear that has some writing in it which is called the prompt. If you click anywhere in that window, you can now begin to write Unix commands. This is the environment in which scientists perform analysis. Let us start by typing the word ‘ls’ (without the quotes), which is short for ‘list’, and hit the carriage return button. Unix will display on the screen the names of anything in your directory. These names are either files or directories.
