Some Linux background

Although the latest versions of +Linux and +Ubuntu and others have GUIs (graphical user interfaces) where you can point and click with the mouse to navigate around the system and applications, the original UNIX system was run from CLI (command line interface).

Why use the CLI?

The advantage a CLI have over an GUI is that it is faster and more powerful, but the downside is that you have to know the commands and how to use them.  Some people may still remember using DOS and may be familiar with typing commands to operate your system, but these days most people operate their computers through GUIs.

Where to start?

Since I’ve recently installed UBUNTU, I am starting to learn the commands and what they do.  It is useful to ask questions and get answers from experienced users on askUbuntu, but I found another great resource on the website:
