Could you folks please clear something up for me. I've never quite understood the gnu of gnu/linux. One way of putting it. If you took the gnu out of gnu/linux, what would you have? For example is the set of commands like "ls", "tail" or "more" part of the core linux or is that what gnu brings. Also, How about vi or vim? vi runs on my android phone but I think that is because I have busybox. So then is busybox a program that simply contains a subset of the gnu utilities. Finally when I think of a distribution like Debian and Ubuntu, is that then linux + gnu + whatever else Debian or Ubuntu has to offer. Where as Andriod is linux + whatever else Android has to offer. Thanks!
