- The title given to this article is incorrect due to technical limitations. The correct title is dir.
In computer software, specifically the command line interface (CLI) of the DOS operating system, dir is a command used for file and directory listing. It is analogous to the Unix ls command.
dir has existed as a DOS command since the initial release of MS-DOS. It is built in to the DOS command shell; in contrast, ls is a standalone program.
Syntax
dir <options> <filelist>
Options
Particular implementations of the DOS operating system may provide more options; these are only the most common.
-
/w : Wide list format
-
/p : Pause at every page
-
/s : Also look in subdirectories
-
/a[xx] : Display files with the specified attributes only
-
/o[xx] : Modifies sort order
Sample listing
This sample is taken from a Windows 2000 implementation of the MS-DOS CLI.
