A Unix/Linux Permissions Refresher

It's easy enough to check, but I don't think that's the case. I have a feeling he was referring to the sticky bit issue somehow.

When I was in apple training, the professor tricked us all with this question:

"Can you delete a read-only file in a directory in which you have write permissions?"

The answer, it appears, is yes... at least in OS X. I find that it's also true in linux. If you can read a file in your home directory, you can delete it.

He explained the semantics of it to us, but I don't exactly remember it.

Hell, I'm not even sure I remember the question correctly.
