Tab completion is ‘da bomb!

I’ve been dinking around with Linux for many, many years now, but I still consider myself a newbie. The work I do do on Linux is 99% command line based and only recently did I learn about tab completion. Why isn’t this feature more publicized? It has made my life configuring my new server so much easier. In a world of case sensitive, obnoxiously long file names, tab completion is the absolute dream!
