Linux Commands

These days, with a Linux distribution like Ubuntu, you can do almost everything without ever needing to use a command line interface.

However, if you really want a fast way to work on your computer to change configurations, install software, or work remotely on another computer, then  the command line is the most efficient way to do it. Many people get scared of the command line interface (CLI) as they are used to using graphical user interfaces (GUI). If you haven't used a CLI before it can be a bit daunting but actually, with practice you may very well find it easier and come to prefer it over using a GUI.

The only key really is to take it slowly, and practice what you have learnt. Don't try and remember everything, just use it what you know and extend it as necessary. It will all come with time.
