The command is available in the command-line interface (CLI) of the operating systems DR CP/M,[2] MP/M,[3] Intel ISIS-II,[4] iRMX 86,[5] MetaComCo TRIPOS,[6] DOS, IBM/Toshiba 4690 OS,[7] IBM OS/2,[8] Microsoft Windows,[9] Singularity, ReactOS,[10] AROS,[11] and in the DCL command-line interface used on DEC VMS, RT-11 and RSX-11. It is also supplied with OS/8 as a CUSP (Commonly-Used System Program).

On MS-DOS, the command is available in versions 1 and later.[12] It is also available in the open source MS-DOS emulator DOSBox.

The numerical computing environments MATLAB and GNU Octave include a dir function with similar functionality.[13][14]

DOS, Windows, ReactOSEdit

List all files and directories in the current working directory.


List any text files and batch files (filename extension ".txt" or ".bat").

dir *.txt *.bat

Recursively list all files and directories in the specified directory and any subdirectories, in wide format, pausing after each screen of output. The directory name is enclosed in double-quotes, to prevent it from being interpreted is as two separate command-line options because it contains a whitespace character.

dir /s /w /p "C:\My Documents"


dir is not a Unix command; Unix has the analogous ls command instead. The Linux operating system, however, has a dir command that "is equivalent to ls -C -b; that is, by default files are listed in columns, sorted vertically, and special characters are represented by backslash escape sequences".[15]
