Root 101 - Concept of Root for Newbies
Fozz writes "One of my colleagues wrote this article explaining the concept of root/super user for Unix newbies. He wrote it after looking for information like it and not finding much. His analogy of Unix and an apartment complex is one of the best metaphors I've seen for understanding multi-user OSes." If you're running any variety of Unix, you've probably been forced to learn this pretty well already, but this is a very lucid explanation to point out to curious friends / co-workers who aren't so sure.
The article says that only root can "Start and stop background processes". Any user can do that, but only root can start and stop processes belonging to other users. Perhaps that is what he meant?
