'''<code>dir</code>''', short for ''directory'', is a [[shell (computing)|shell]] [[command (computing)|command]] for listing [[file system]] contents; [[computer file|files]] and [[file directory|directories]].<ref>{{cite book|url=http://archive.org/details/1988-rugheimer-spanik-amigados-quick-reference|title=AmigaDOS quick reference|first1=Hannes|last1=Rügheimer|first2=Christian|last2=Spanik|date=October 22, 1988|publisher=Grand Rapids, Mi : Abacus|isbn=9781557550491|via=Internet Archive}}</ref> Arguably, the command provides the same essential functionality as the <code>[[ls]]</code> command, but typically the two commands are described as notably separate concepts, possibly since {{code|ls}} is implemented from a [[codebase]] that shares more history than many {{code|dir}} implementations.

The command is often implemented as internal in the [[operating system]] [[shell (computing)|shell]] instead of as a separate application as many other commands are.
