Bash Shell commands quick reference

I've been using www.ss64.com for several years to remember:

(1) Windows NT, 2000, XP, 2003, etc shell commands
(2) Oracle PL/SQL syntax
(3) Bash Shell commands

Here is a link to the Bash Shell commands: Linux commands

I also noticed while composing this post they have a SQL Server 2005 section. That is news to me. I recommend using this reference for either the Windows or bash shell in a 'what was that command syntax sort of moment'.
