>Rebooting means booting the system again. This can be
accomplished by first shutting it down completely, turning
power off, and then turning it back on. A simpler way is to
ask <B
CLASS="COMMAND"
>shutdown</B
> to reboot the system, instead
of merely halting it. This is accomplished by using the
<SPAN
CLASS="OPTION"
>-r</SPAN
> option to <B
CLASS="COMMAND"
>shutdown</B
>,
for example, by giving the command <B
CLASS="COMMAND"
>shutdown -r
now</B
>.</P
><P
>Most Linux systems run <B
CLASS="COMMAND"
>shutdown -r now</B
>
when ctrl-alt-del is pressed on the keyboard. This reboots the
system. The action on ctrl-alt-del is configurable, however, and
it might be better to allow for some delay before the reboot on
a multiuser machine. Systems that are physically accessible to
anyone might even be configured to do nothing when ctrl-alt-del
is pressed. </P
