In computing, ls is a command to list computer files and directories in Unix and Unix-like operating systems. It is specified by POSIX and the Single UNIX Specification.

It is available in the EFI shell,^[1] as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities,^[2] or as part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2.^[3]

The numerical computing environments MATLAB and GNU Octave include an ls function with similar functionality.^[4][5]

In other environments, such as DOS, OS/2, and Microsoft Windows, similar functionality is provided by the dir command.
