in thread Need help understanding code snippet with "grep -f"
Well, I did read it, but I couldn't figure out what the -f does there, and how the behaviour of grep described in the docs would give me a list of existing files. But that's probably cleared up now. Is there also documentation on this "-f" thing? Because it's really hard to google for something as short as "-f"...
