<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>/run/nologin</filename> file is created to
|
|
ensure that further logins shall not be allowed.</para>
