What are some good websites for reference on Unix commands?

Question

I just start using Unix and terminal, and find myself constantly typing searches for individual unix command references. I'm wondering if you guys had any specific sites that you use for most of your reference that I could just bookmark and search. Figure it could possibly save some time.

Answer 1

I always just Google for

man whatever

and the first hit is almost always the appropriate manual page.

Answer 2

Check out commandlinefu

Answer 3

Linux Man Pages online is a great reference. TLDP.org is also excellent, not only do they list the commands but many examples on how to use them.

Answer 4

I myself use these 2 sites:

http://www.math.uic.edu/

http://www.oreillynet.com/

Answer 5

This site is a decent command line reference for Linux, Mac OS X, PowerShell, Windows XP, SQL Server, and Oracle:

SS64

Answer 6

This is very comprehensive: Unix/Linux command overview

Answer 7

An easy and fast solution solution to get information about a command is to use the local information.

man <command>

And if you don't know the command the command, you could search for it using

man -f <keyword>

or it's equivalent

whatis <keyword>

Answer 8

This website covers a pretty good range. It's a bit slow, and maybe too gentle, but good for starting from scratch: http://www.ee.surrey.ac.uk/Teaching/Unix/

For sed, I like this one: http://www.grymoire.com/Unix/Sed.html

(The rest of his site has lots more: http://www.grymoire.com/Unix/)

For find, here's a start: http://content.hccfl.edu/pollock/Unix/FindCmd.htm

It's a dead-tree thing, but I also highly recommend The Linux Phrasebook by Scott Granneman.
