Sorry for the anonymous post. I thought I was logged in when I hit submit.

In response to the first poster, I am not a college student and this is not a home work assignment.

I work for a CAD company and do software support. I often get log files from customers that i need to debug. I want to write a script to extract the commands the customer ran. I can get a list of the valid command via help. However the UI allows the commands to be abbreviated.

I have over 20 years experience with Perl but I did not quite know how to solve the problem. So instead of spinning my wheels, I decided to leverage perl monks.

Thank you everyone for other posts, they were the type of ideas I was looking for.
