These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.

<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>
