In computing, dir (directory) is a command used for computer file and directory listing[1], specifically in the command line interface (CLI) of the operating systems CP/M[2], MP/M[3], DOS, OS/2, Singularity, Microsoft Windows, ReactOS, AROS[4] and in the DCL command line interface used on VMS, RT-11 and RSX-11.

The command is also supplied with OS/8 as a CUSP (Commonly-Used System Program) and available in the open source MS-DOS emulator DOSBox.


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".[5]
