Unix script to insert lines in a file

I've been using Linux for several years and have created several bash functions and scripts to do various things. This particular problem is one I have not been able to figure out by myself or by searching on forums. That's exactly what I was looking for. It's amazing how simple and powerful a few lines of code are.

Find repeated word on different lines, add number to the repeated word, plus write changes to the original file Shell Programming and Scripting. Thank you. Anyhow hope it helps.
