Some Common Linux Commands

Linux has a well-developed graphical user interface – in fact it has several GUIs, the most popular of which are Gnome (on which Ubuntu is based) and KDE (Kubuntu‘s desktop).  But Linux also has a powerful command-line interface – also known as the console or terminal – and a great many commands to use in the CLI.
Here’s a little “cheat sheet” of common, basic Linux commands – just to get you started – you’d be wise to study this subject further if you’re serious about administering a Linux box.
