The trick is that you loose access to every file on the system. chmod is also a file. And ls. And sudo. You see where it’s going. System will kinda work after this command, but rebooting (which by a coincidence is a common action for “fixing” things) will reveal that system is dead.
sudo chmod 000 -R /is very fun way of braking your system and is not widely known 🙂What does this do? nobody can read any file? would sudo chmod 777 fix it at least to a usable system?
