Dir (DOS command)
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. In Unix, dir is a symbolic link to or an alias for the 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.
