I found this: http://fosswire.com/2007/08/02/unixlinux-command-cheat-sheet/
A neat little PDF command line tool. I downloaded mine to the desktop where it is always at my finger tips, or better yet open it after you boot up and leave it open.
I know, some people do not like to mess up their destop, including myself. Some times there has to be exceptions in my case.
Just wanted to share this with everyone.
