A command prompt is a non-graphical interface that allows you to interact with your operating system. At the command prompt, you enter commands by typing their names followed by options and arguments. Most modern computers use a graphical user interface (GUI), which allows users to more intuitively access programs and documents. However, some programs and commands are still only available only through a command prompt. To access the command prompt, follow the instructions appropriate to your operating system.


To access the command prompt in Windows, in Windows 7, click the Start button and enter cmd. In other versions, from the Start menu, select Run... and then enter cmd.
