Re: File and directory permissions




Tomas and Dan, thanks for the explanations. So if the process have already a handle (file descriptor) to apple, it can continue using it, even when I chmod 700 one of its parents. On the other hand, any new process trying to get a handle to apple MUST traverse the directory tree. This is what I understand. Thanks again for the explanations.

Think of it as being somewhat like a parking lot / garage with a gate at the

Uh-oh. A car analogy :)
You enter the lot / garage, get your ticket, and are admitted in. Now
you're free to go anywhere in the lot to find a space (equivalent of
opening / editing files).

While you're driving around the lot, the attendant closes the gate and
puts up a "Lot Full" sign [...]

Nice metaphor, thanks!

Cheers
