Editing Mkdir (section)

==History==
In early versions of Unix ([[Berkeley Software Distribution|4.1BSD]] and early versions of [[System V]]), this command had to be [[setuid]] [[superuser|root]] as the [[kernel (operating system)|kernel]] did not have an <code>mkdir</code> [[syscall]]. Instead, it made the directory with <code>[[mknod]]</code> and linked in the <code>.</code> and <code>..</code> directory entries manually. The command is available in [[MS-DOS]] versions 2 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> [[Digital Research]] [[DR DOS 6.0]]<ref name="drdos6userguide">{{Cite web |url=https://www.4corn.co.uk/archive/docs/DR%20DOS%206.0%20User%20Guide-opt.pdf |title=DR DOS 6.0 User Guide Optimisation and Configuration Tips |access-date=2019-08-13 |archive-url=https://web.archive.org/web/20190930135943/http://www.4corn.co.uk/archive/docs/DR%20DOS%206.0%20User%20Guide-opt.pdf |archive-date=2019-09-30 |url-status=dead }}</ref> and [[Datalight]] [[ROM-DOS]]<ref>{{Cite web|url=https://www.datalight.com/assets/files/ROM-DOS_Users_Guide.pdf|title=Datalight ROM-DOS User's Guide|website=www.datalight.com}}</ref> also include an implementation of the {{code|md}} and {{code|mkdir}} commands.

The version of <code>mkdir</code> bundled in [[GNU]] [[coreutils]] was written by David MacKenzie.<ref>{{cite web|url=https://linux.die.net/man/1/mkdir|title=mkdir(1): make directories - Linux man page|website=linux.die.net}}</ref>
