Noob question about chmod 777 and 775 : rlinux4noobs

chmod 777You almost never need 777 permissions on any type of file, and you absolutely never need 777 on a non-executable file. – skiphoppy Commented Apr 4, 2012 at 10:51I'm trying to change the permissions of temp_dir to 777. Why are these commands not accomplishing that? I'm using Linux by the way.
