How can I create (if the folder is new) or change (if the folder was already existent) permissions for a folder?In particular, I want to create a subdirectory in /etc/bind/ where I can put the  named_dump.db file, so I've to create the new directory with write permission for bind user and group.First of all, is it right?And if I want to change /etc/bind/ permissions and save there named_dump.db?
