We’re going to use some terminal commands throughout the course of this article. If you’re a new Linux user, don’t be scared—Linux’s powerful command line makes it easy to follow instructions you’ll find in articles like this one. Instead of following a list of long steps telling you to click here and click there, you can just copy and paste these commands into a terminal window and hit Enter.
To open a terminal, press the Windows key (known as the Super key in Linux), type Terminal, and press Enter. You can also click the Ubuntu logo at the top-left corner of your screen instead of pressing the Windows key.
