I've updated the presentation notes for the March OCLUG talk on
Shell Programming with the questions and added some references.
They're accessible from this page:
http://devel.oclug.on.ca/wiki/MeetingPresentations2011
Prepared on short notice, it was intended to be a new to Linux level talk
but is possibly missing some details that would allow a beginner try the
suggestions presented.
Feel free to ask any questions.
