running a task every five minutes without overlapping?

Question

Quoting https://laravel.com/docs/5.1/scheduling#preventing-task-overlaps ,

$schedule->command('emails:send')->withoutOverlapping();

In this example, the emails:send Artisan command will be run every minute if it is not already running.

What if I wanted the task to run every five minutes instead? Could I do this?:

$schedule->command('emails:send')->everyFiveMinutes()->withoutOverlapping();

Yes you can do this. command returns an instance of Event the underlying code for Event has a fluent interface which allows you to chain these together in this way.

You can see this for yourself if you look at the withoutOverlapping method.

/**
 * Do not allow the event to overlap each other.
 *
 * @return $this
 */
public function withoutOverlapping()
{
    $this->withoutOverlapping = true;
    return $this->skip(function () {
        return file_exists($this->mutexPath());
    });
}
