This was a nice read and a good introduction to text processing with unix commands. I agree with the other user re python usage - that you may as well use it for the whole task if you're going to use it at all - but I don't think it's a major flaw. It worked for you right? I would suggest naming the python file a bit more descriptively though. Interesting to read the other suggestions about dealing with this without python.
