title: How to get notified when crontab fails
body: <p>Trying to detect if my crontab job fails and if so I would want it to notify me but I could not find any information on that but the following from the old crontab.guru. What does the following mean?</p>
  
  <p><code>&amp;&amp; curl -sm 30 k.wdt.io/&lt;email-address&gt;/&lt;cronjob-name&gt;?c=</code></p>
  
  <p>Is there a good way to create a script in case crontab fails?</p>
  
  <p>Using Mac OS</p>
