# Rebooting and Shutting Down

The system can be shut down (and automatically powered off) by doing:

    # shutdown

This is equivalent to running `systemctl poweroff`.

To reboot the system, run

    # reboot

which is equivalent to `systemctl reboot`. Alternatively, you can quickly reboot the system using `kexec`, which bypasses the BIOS by directly loading the new kernel into memory:

    # systemctl kexec

The machine can be suspended to RAM (if supported) using `systemctl suspend`, and suspended to disk using `systemctl hibernate`.

These commands can be run by any user who is logged in locally, i.e. on a virtual console or in X11; otherwise, the user is asked for authentication.
