List of DOS commands

This article lists notable commands provided by the MS-DOS disk operating system (DOS), especially as used on an IBM PC compatible computer. Other DOS variants as well as the legacy Windows shell, Command Prompt (cmd.exe), provide many of these commands. Many other DOS variants are informally called DOS, but are not included in the scope of the list. The highly related variant, IBM PC DOS, is included. The list is not intended to be exhaustive, but does include commands covering the various releases.

Each command is implemented either as built-in to the command interpreter, COMMAND.COM, or as an external program. Although prevailing style is to write command names in all caps, the interpreter matches ignoring case.
