Get to Know Your Computer

Every app you use is a picture of your computer. The terminal is the computer with the picture taken off.

On a Mac press command and space. On Windows use the search box on the taskbar. Type terminal, press enter. The blinking line is the cursor, and it means your turn.

You already know this screen. Every one of those folders is a room in your computer, and the terminal is another door into the same building.

Your computer is a building full of rooms. Type cd to see which one you are in, and mkdir to build a new one. It prints nothing on success.

It looked like nothing happened. Open your file manager, go to the same place the terminal said you were standing, and there it is.
