Hi,
Thanx for the suggestions. I understand that the job can be done by different variations of scripts, but what I am eager about is "a single command/command pipe" which can do the job. If there are only specific number of entries in each line, i can manually compare them in command-line using awk/perl. But since I dont know the no. of entries in each line, the task is cumbersome.
I would be enlightened if I get a command pipe version of these scripts.

Thanks
Srini
