You don't need to understand how sudo works to know what it does. If you didn't know that running `sudo cat someFile` will leak the contents of the file, then this list is at the wrong level, and probably won't help you.

I'm not hating on people for not knowing things - it just seems like either its already obvious and this won't help you or its not obvious and it still won't help you because its not really teaching you the right thing. Either way, it seems kind of silly.
