ctrlaltdel

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
