The Graphical User Interface

Why use the Command-Line? Fast. Efficient. Powerful. Scripting language. Remote access. Almost Anything you can do in the GUI, you can do on the command line: Listen to music. Read email. Browse the web. Watch movies (kinda: towel.blinkenlights.nl).

The Filesystem One root to rule them all

The Filesystem Different devices, same root
