Hi all,
I have a basic procedure that i want to create..
Assuming that I have 2 files.
In each file i have list of 30 words.
i want to lookfor the first word in list 1, if it found also in list 2.
if it is, keep the line number in file.
if not, keep the word in different file.
Any idea on short/easy solution?

Thanks,
Pap

using grep (with -n option) within a while loop will probably get what you want.
