Before running this
This is a reference for Bash; commands do not run on this page. Use the matching shell on your own computer. Read the example, expected result and notes before trying it. New to terminals? Start with the shell basics.
Syntax
UPPERCASE words are placeholders to replace. Brackets in the syntax line describe optional arguments; do not type those brackets literally.
mkdir [-p] DIRECTORYExample
mkdir auwen-labExpected result
A new empty directory; success normally prints nothing.
Notes and traps
-p creates missing parents and accepts existing directories; use it deliberately.
