There are basic Linux commands that are going to be very useful in your navigation through your filesystems through the Terminal. In this section, I want to list some essential commands that will help you when building the Magic Mirror. With each command, I’ll provide a brief explanation. As with anything, the best way to learn how to successfully use these commands is with practice. Also, note that syntax is important when working with the command line. The computer interprets capitalized and uncapitalized letters as two different symbols, so we have to make sure we type our commands as they are shown. A good rule of thumb is that if something doesn’t work the first time, go back and proofread what you have typed.
