Hi.. this is `hostname -f`:/root/bin/bad_devs_bad.sh

It seems someone has been silly and set the following bad permissions :/

Please clean this up -`hostname -f`

EG:

find /www -type d -perm 777 -exec chmod -c 775 {} \;
find /www -type f -perm 666 -exec chmod -c 664 {} \;

#count how many bad dir's were detected
