What is a Command Prompt?

A command prompt is a working prompt in the operating system that prompts for command input. The command prompt varies under different operating system environments. In the Windows environment, the command line program is cmd.exe, which is a 32-bit command line program. Microsoft Windows is based on the command interpreter on Windows, similar to Microsoft's DOS operating system. ^[1]

Generally speaking "command line" means linux

CMD is a command-line program for Microsoft Windows and a link to enter the command prompt window. Enter the command prompt window through the CMD command, and the version and copyright information of Windows will be displayed. You can easily access other sub-applications by using CMD commands. CMD is a 32-bit command line program that runs on Windows nt2000XP. ^[7]

When I first contacted the computer, I started with the DOS system. In the DOS era, there was no window operation interface like Windows. There was only a dark window for you to enter commands. Therefore, to learn DOS system operation, the command prompt is indispensable. I can tell everyone that most programmers or computer experts operate very well under the DOS system, so if novices want to become computer masters, DOS commands must be learned.

Until today's Windows system, the operation of DOS commands is still inseparable. To learn DOS system operation, first understand the command prompt. Learn what each command prompt does before you can use it flexibly. ^[5]

Windows XP click "Start All Accessories

On Windows systems, you can disable the command prompt for security reasons. Take Windows XP as an example to introduce the operation method:

Open the Group Policy Editor window, expand the User Configuration Administrative Templates directory in the left pane and select the System directory, then set the Block Access to Command Prompt policy in the right pane to "Enabled" status. When this policy is enabled, when users try to open the Command Prompt window, a prompt message will pop up to block the user's operation. ^[9]
