DOS Commands

How well do you remember the DOS (and Windows) command line?

Some utilities are unique to MS-DOS. Names from PC DOS and DR-DOS are supported.

Darker cells indicate commands no longer supported in the Windows command line.

One utility is included in 32-bit, but not 64-bit versions of Windows.

Bonus trivia: Two files that everyone had to work with in DOS.
