Utility to control what happens when CTRL+ALT+DEL is pressed.
- Get current setting:
ctrlaltdel
- Set CTRL+ALT+DEL to reboot immediately, without any preparation:
sudo ctrlaltdel hard
- Set CTRL+ALT+DEL to reboot "normally", giving processes a chance to exit first (send SIGINT to PID1):
sudo ctrlaltdel soft
