From: hadi motamedi <motamedi24 at gmail.com> > Can you please do me favor and let me know if I can go further and try for advanced search like finding how many rows inside a file have data that does not start with a zero after the third comma ? Something like: awk -F, ' { print $4 } ' | grep -v "^0" | wc -l Use one command at a time to see how they work with each other (you might have to modify the grep a bit)... JD
