Introduction to the Command Line

Why use the Command Line?

GUIs and great for novice users: they allow people to get using a system without having to read a huge manual. However, there comes a time when the numerous mouse clicks to complete a task become a hinderance and where it is quicker to just bring up a terminal window and type in the command directly.

Where the command line (-also know as a "terminal window", "console", etc) comes into it's own is with automation and scripting: it's possible (-and will make your life so much easier) if you take common tasks and bundle the commands into one or more shell script (.sh) files, which can then be scheduled or added to the desktop or taskbar to run.

Linux systems traditionally use the bash shell. This stands for Bourne Again SHell - which is a pun on the Bourne shell used by many Unix systems.

A great in-depth Linux bash tutorial can be found at, so we shall just give you a flavour of the subject here.
