No problem to skip this. As a followup, here is the perl code for the
second solution, which is cleaner anyhow. As pointed out by you and
others, it is no problem not to react on the shutdown script call, it
will be repeated.

Checking if nobody is logged in and furthermore shutting down:

------------------------vdrsettime--------------------------------
$whos = `who | wc -l`;

if ( int($whos) == 0 )
{
   # nobody logged in -> shut down
   system( "nohup sh -c \"(sleep 10; killall -HUP vdr) \" &" );
}
-----------------------------------------------------------------
