basic 6 question

its about unix, one i have never used before. i used windows and dont quite sure about command. should i install unix to pass , or should i bypass this one?

Best way to pass is to google for unix commands. Read the article the mission and the forums. You don't need to install anything.Very simple mission:D

Simple if you're used to unix, jerk XD I hardly know any unix commands. I know the basic (ls, chmod, rem, etc.) but I don't know anything about their file structure and I have no idea what this "other file that tracks people" is >.< I'm searching google to figure out just how unix logs things.

EDIT- my bad, it's "rm", not "rem" ^^;; Like I said- I hardly know any unix commands XP
