Directory listing: names, sizes, dates	dir	ls -al ("l" for long) ls -a -l
Ditto, sorted by date of file	dir /od	ls -alt ("t" for time)
Ditto, pausing between screens	dir /p /od dir /od | more	ls -alt | more (BSD) ls -alt | pg (V.3)
Display contents of a file	type file	cat file
Ditto, pausing between screens	more <>	more file (BSD) pg file (V.3)
Print a file on the default printer	print file copy file prn:	lpr file (BSD) lp file (V.3) print file (AIX)
Edit a file in full-screen mode	edit file	vi file (#1 editor) emacs file (#2) pico file (easiest)
Create a directory	mkdir dir md dir	mkdir dir
Change current directory	cd dir cd dir\sub	cd dir cd dir/sub
Change to parent directory	cd .. cd..	cd ..
Change to root directory	cd \ cd\	cd /
Change to HOME directory (where you start when you login)	(NOT APPLICABLE)	cd cd /u/userid (Some systems instead use: "cd /home/userid")
Display name of current directory	cd	pwd
Display directory, and subdirectories	dir /s tree /f	ls -R find . -print
Ditto, but not the files	tree	find . -type d -print
