Stupendous!
Works like a charm, Thanks!

If you dont mind, can you just explain a little bit of that sed command you used, agn?

I have a beginner level of understanding. What i read in a book about sed like if there is an expression,
sed 's/\([a-z]*\).*/\1/'
then \1 remembers the second part of the pattern matched.

But in your answer you have used 3 *s. so that means three patterns? Also could you explain why we use '\' before parenthesis? And what is the significance of the expression inside parenthesis?
