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.
