Using the command line
Some of the instructions in this guide ask you to type commands into the
command line (Terminal). You can find the Terminal application in
the Activities overview.
If you are not familiar with using a command line, don’t worry — this
guide will direct you at each step. All you need to remember is that
commands are case-sensitive (so you must type them exactly as they
appear here), and to press Enter after typing each command to
run it.
