Using Beamer Animations to simulate Terminal Input and Output

I've been meaning to write about this for some time.  A few months ago, I had to prepare some training material on Unix basics and such.  While beamer was a natural choice for the presentation, I wanted to show some nifty animations that showed the commands and outputs as typed in a terminal.  I had the written text all done up but didn't know how to get the animation correct; I had misunderstood the features of animate package on CTAN.

Being stuck, I posted on tex stackexchange and had a beautiful solution from Alexander Grahn who went out of his way to solve my different issues that I had with my code.  Finally, on a beamer slide, you can now autoplay simulated Unix commands and expected output while giving a talk, instead of doing uncover on mouse click in beamer.

If you want to see my code instead of the one posted on the stackexchange site, do email me and I shall mail it separately.

EDIT: the compiled PDF can be found here, as requested. Of course you have to download it and open it in Reader for you to see the animations; it won't work in the web preview.
