Some people might wonder how you could use the $-sign in the echo command given that the $-sign is used to call a variable. Use the escape-character \ in front of it. This applies in general if you struggle to use a character in a command, like the space or slash.

Great series. The intro is longer than my ADHD can cope with, so I skip ahead right away. But the presentation is fantastic.
