<title>Rebooting and Shutting Down</title>
<para>
The system can be shut down (and automatically powered off) by
doing:
</para>
<programlisting>
# shutdown
</programlisting>
<para>
This is equivalent to running <literal>systemctl poweroff</literal>.
</para>
<para>
To reboot the system, run
</para>
<programlisting>
# reboot
</programlisting>
<para>
which is equivalent to <literal>systemctl reboot</literal>.
Alternatively, you can quickly reboot the system using
<literal>kexec</literal>, which bypasses the BIOS by directly
loading the new kernel into memory:
</para>
<programlisting>
# systemctl kexec
</programlisting>
<para>
The machine can be suspended to RAM (if supported) using
<literal>systemctl suspend</literal>, and suspended to disk using
<literal>systemctl hibernate</literal>.
</para>
<para>
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.
</para>
