Please write and send me your shell script

Try re-writing either your Python or Perl program as a shell script, or else one of the other assignments that you have done for this part of the course. Make sure you choose something that is at least a little challenging -- it's not that interesting to just put three awk commands into a shell script and be done.

Chances are good that you can do anything you have done so far in the course with just a shell script. If you want to include more advanced shell scripting techniques, feel free.
