Pid of scheduler task in Laravel 5

I have added a task to the Scheduler in app/console/kernel.php. Like so:

$schedule->command('atomaton:socket_start --port=8080')
     ->withoutOverlapping()
     ->appendOutputTo(base_path().'/atomaton/storage/atnSocket.log');

So my question is: How do I find out if that command is running? Can I get the PID?
