Run a command on a schedule and verify that it has run
You can use Automator to create a "Calendar Event". You can use the Utilities &gt; Run Shell Script action to run your desired script, and then use Utilities &gt; Display Notification to show that the script ran.

When you save the workflow, it will show a dialog asking you to name the event, and will then automatically place an event in the calendar and act accordingly. You can then change that event's time and repeat frequency.
