This script is to help you to restore your Unix system if you have accidentally executed chmod -R user:user or chmod -R 777 in your unix system ('user' as as username for your system).
Usage:
Place the script inside the parent folder (/ for whole system) then chmod this script:
chmod +x getmod_getowner_allfiles.sh
then execute it:
./getmod_getowner_allfiles.sh
When this is being done - a new file will be created in name of 'restore-chmod-chown.sh' and it'll be already executable (chmod +x restore-chmod-chown.sh will be already perform by the script). Place the new script right inside the parent folder of your system i.e. / ).
Voila!
This will only work if you have performed this script earlier before the accident.
Recommendation: perform this script at the end of fresh installation of your system, and archive the newly created restore-chmod-chown.sh somewhere safe in your system (i.e. USB or cloud).
