How would I recursively change files with 777 permissions to 755?

[smithaa02]

Basically, I have a number of files in /home/virtual/mysite.com/var/www/html/catalog that I need to change from 777 to 755. The key is that I only want to change files that have 777 permissions. Files with say 444 I don't want change to 755.

Is there an easy way to do this?

find /home/virtual/mysite.com/var/www/html/catalog -perm 777 -exec chmod 755 {} \; -print
