A Lines of Code Counter

The script below is a simple lines of code counter for you. Following interesting features of the script are:

1. It recursively counts the lines of code within all subdirectories of the location mentioned.
2. It counts the lines of code of only those files whose extensions are considered as source file name extensions in the list srcFileExtensions defined early in the script.
3. Optionally, you could make it exclude the blank lines from the lines of code.

Caution: The script doesn't run like lightning! Suggested optimisations will be gratefully accepted.

Also, there are plenty of superior LOC tools out there. Just google! But for simple plain lines of code counting, this one would still be good for you to begin with. Just copy paste into a bash shell script and go!
