Unix

Hey guys, I am in my first year of computer programming at seneca college or I am having trouble with the unix course. I just had a test or got 38% on it! I need mad help from here to pass this! How does grep work? I do not understood? Also what is this about super hex or oct? Or what is this permissions thing? My programming experience is totally in rpgmaker guys, so help would be apprieciated!

(if you help me I will include you in my rpg that I am making in rpgmaker 2000!)

Thanks in advance

Also sorry if my english is bad

I'm not even going to google this copypasta

man grep
go to rpgmaker 2000 if you want to do only that, not learn unix.
hex and oct are ways to count numbers.
permission is who can write what on file, like me getting into your ass.

This is an old one. I'd be impressed, expect that I see the lowercase version got posted to /g/ earlier today, and that's probably where >>1-kun got it.
