I know it sounds kind of stupid, but I was told to delete some files off the
server at work, and when I told my boss, I wasn't the owner, and that I
could only delete them if I got root, she told me she would delete them.
Since my boss and I have practically the same access privileges, I wanted to
know how she could do that. She said that the guy who actually has root gave
her a special command that allows her to do that. I immediately saw the
potential security problem, so I thought I'd find out how something like
that would work. Ed
