There are a lot of good reasons that the command prompt DOS shell will never die.  I have over the years been pretty deep into DOS batch files but how easily I forgot things I don't use every day!  Well here is a web site (http://www.onesmartclick.com/programming/batch-files.html) that I found that is pretty useful in remembering these cryptic commands.  I'm going to try to dig up some of my old scripts to post as well to look back on.
