<title>Description</title>
|
|
|
|
<para><command>shutdown</command> may be used to halt,
|
|
power-off or reboot the machine.</para>
|
|
|
|
<para>The first argument may be a time string (which
|
|
is usually <literal>now</literal>). Optionally, this
|
|
may be followed by a wall message to be sent to all
|
|
logged-in users before going down.</para>
|
|
|
|
<para>The time string may either be in the format
|
|
<literal>hh:mm</literal> for hour/minutes specifying
|
|
the time to execute the shutdown at, specified in 24h
|
|
clock format. Alternatively it may be in the syntax
|
|
<literal>+m</literal> referring to the specified
|
|
number of minutes m from now. <literal>now</literal>
|
|
is an alias for <literal>+0</literal>, i.e. for
|
|
triggering an immediate shutdown. If no time argument
|
|
is specified, <literal>+1</literal> is
|
|
implied.</para>
|
|
|
|
<para>Note that to specify a wall message you must
|
|
specify a time argument, too.</para>
|
|
|
|
<para>If the time argument is used, 5 minutes
|
|
before the system goes down the
|
|
<filename>/etc/nologin</filename> file is created to
|
|
ensure that further logins shall not be
|
|
allowed.</para>
