I read here that
chmod -R 777 / is a really bad idea, because it overwrites permissions on files, and erases sticky bits and
setgid and stuff.
However I was thinking that
chmod -R ugo+rwx / would not overwrite the permissions but add them, if not there already present, and that it would be therefore much safer than the aforementioned command.
Am I right? Or are those commands basically the same and both would destroy my system?
I don't intend on doing it, just asking for general culture.
