The online book, Data-Intensive Linguistics, by Chris Brew and Marc Moens, has a nice introduction to using UNIX tools for linguistic processing. You may wish to have a look at it and adapt some of what's there, or just link to it in a "Resources" or "Further Reading" section.
As a member of pedagogues, I also want to thank you for thinking of contributing to our Tutorials section. Once you've hammered out a final version based on comments in this thread, you should, IMHO, feel free to post it as a Tutorial. (Maybe after running it through pod2html or something, though...) :-)
HTH,
Update: This link, on the page noted above, may also be useful...
