This article presents a list of commands used by MS-DOS compatible operating systems, especially as used on IBM PC compatibles. Many unrelated disk operating systems use the DOS acronym and are not part of the scope of this list.
In MS-DOS, many standard system commands are provided for common tasks such as listing files on a disk or moving files. Some commands are built into the command interpreter; others exist as external commands on disk. Over multiple generations, commands were added for additional functions. In Microsoft Windows, a command prompt window that uses many of the same commands, cmd.exe, can still be used.
