I...uh...need to see it. MABB 7.7.7 it's imperative that progress is made. We need updates for peace of mind going forward. Just my thoughts a feelings on it. I can offer free binary code if you run out.
777 permissions are generally not recommended as they grant too much access
rwx (read, write, execute)
111 (1 for on, 0 for off)
and in binary we get, in order 4,2,1, add em' up
7 for all the permissions
we end up with 3 digits for users, group owner, and owner
hence 777
