Bash script to recursively obtain file and directory permissions, compare them to desired permissions and return if correct or not

I am trying to write a script which would retrieve the permissions of a group of files and directories. Then check each permission to see if they are set correctly. If the permissions are not set correctly then I would like it to echo which directory or group of files permissions were incorrectly set. I have used find to recursively find all files and directories inside a certain directory and then execute stat to return the current permissions. From the returned list of permissions I then use an if-then statement to check if any files or directories have unexpected permissions. This is accomplished by the != operator and using pattern matching. So all files should have permissions set to 444 and directories to 555 and if not return that the permissions are wrong. for site in $(echo /var/www/*) do permcheckfile=$(find $site -type f -exec stat -c '%a' '{}' +) permcheckdir=$(find $site -type d -exec stat -c '%a' '{}' +) if [[ $permcheckfile != *444 ]] then echo "$site file permissions are wrong" else echo "$site file permissions are correct" fi if [[ $permcheckdir != *555 ]] then echo "$site directory permissions are wrong" else echo "$site directory permissions are correct" fi done The problem found with the script above is sometimes it will return false positives. Where I am going wrong? Is there a better way?
