in thread Need help understanding code snippet with "grep -f"

Is there also documentation on this "-f" thing? Because it's really hard to google for something as short as "-f"...

yup, it can be, but here is a tip, if you use perldoc://"-f" in perlmonks search box its like "-f" site:perldoc.perl.org -> http://perldoc.perl.org/functions/-X.html
