The <code>dir</code> command is supported by [[Tim Paterson]]'s [[Seattle Computer Products|SCP]] [[86-DOS]].<ref>{{cite book |title=86-DOS - Disk Operating System for the 8086 - User's Manual |edition=Preliminary |version=Version 0.3 |date=1980 |publisher=[[Seattle Computer Products, Inc.]] |location=Seattle, Washington, USA |url=http://www.patersontech.com/Dos/docs/86_Dos_usr_03.pdf |access-date=2019-07-14 |url-status=dead |archive-url=https://web.archive.org/web/20190714004434/http://www.patersontech.com/dos/docs/86_Dos_usr_03.pdf |archive-date=2019-07-14}} (59 pages)</ref> On [[MS-DOS]], the command is available in versions 1 and later.<ref name="RUNNINGMSDOS">{{Cite book|author-last=Wolverton|author-first=Van|title=Running MS-DOS Version 6.22 (20th Anniversary Edition), 6th Revised edition|date=2003|publisher=[[Microsoft Press]]|isbn=0-7356-1812-7}}</ref> It is also available in the [[open-source software|open source]] MS-DOS [[emulator]] [[DOSBox]].

The [[numerical analysis|numerical computing]] environments [[MATLAB]] and [[GNU Octave]] include a <code>dir</code>
