Find files on certain directory for excluding files certain permission

Why is this useful? When your directory contains thousands of files.
Yes, CHMOD is slow and surprisingly very I/O taxing.
So being able to use 'find' command first to only CHMOD certain files
that needs to be CHMODED is useful.


find /your_directory ! -perm 0777

-OR-

find /your_directory \! \( -perm 0777 -o -perm 0775 \)
