ctrlaltdel

Utility to control what happens when <Ctrl Alt Del> is pressed. More information: https://manned.org/ctrlaltdel.

  • 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
