Graphical User Interface (GUI) vs. the old 'command line'

Short demonstration of how the command line interface still accessible in Windows 7 looks and works for the benefit of people only familiar with a modern graphical user interface (GUI). Created with the Hypercam 3 screen capture utility as a demonstration of its use.

The Command Prompt in Windows isn't a "real" CLI. For example, you can't control the whole operating system with the Command Prompt. In Linux, for example, you can control the whole system with both using the GUI or the Terminal. But Windows has had only a CLI, the latest version was MS-DOS 6.0, which came in 1993. Some Linux distributions don't even have a GUI!
To answer your question, the command "ls" in the Terminal (Linux) lists files and folders in much the same way as "dir" does in Windows
