Ls: Measurement, Overview & Behavior

ls is a shell command for listing files – including special files such as directories. Originally developed for Unix and later codified by POSIX and Single UNIX Specification, it is supported in many operating systems today, including Unix-like variants, Windows (via PowerShell and UnxUtils), EFI, and MSX-DOS (via MSX-DOS2 Tools).
