... Additionally, the old favourite rm -rf / has potentially become even more lethal than it used to be if your PC is UEFI. Essentially it can remove from the /sys directory, the firmware that UEFI needs to boot from external media. One bricked PC with no recovery!

The video demonstrates that in Ubuntu distros the rm -rf / command has been disabled.

};
fork

Also, unless you can deploy it to run at boot, it only needs a hard reset to get rid of it. Additionally, the old favourite rm -rf / has potentially become even more lethal than it used to be if your PC is UEFI. Essentially it can remove from the /sys directory, the firmware that UEFI needs to boot from external media. One bricked PC with no recovery!
