Also thanks a lot for unix forum guys "you ppl rock!!!"

FYI, i was trying to search for this code since all the weekend and went through sed manual "http://www.grymoire.com/Unix/Sed.html" sub topic (/1, /2, etc. Specifying which occurrence) however was unlucky in trying all the trial and error method.

Also Summer could you please explain me the code you have written so that i can understand it in a better way.

Again thanks a lot and you can close this thread.

Thanks
