  <pre><code>php ls -al &lt;your Magento install dir&gt;/var/.setup_cronjob_status
  </code></pre>
  
  <p>It is showing the following response.</p>
  
  <pre><code>Could not open input file:ls
  </code></pre>
  
  <p>I also tried the below code </p>
  
  <pre><code>php crontab -u magento2.1 -l
  </code></pre>
  
  <p>&amp;</p>
  
  <pre><code>php crontab -u Admin -l
  </code></pre>
  
  <p>where <strong>magento2.1</strong> is the <strong>user name</strong> of my Magento &amp; <strong>Admin</strong> is my <strong>system name</strong>.
  Both the code given an error as follows</p>
  
  <pre><code>Could not open input file:crontab
  </code></pre>
  
  <p>I am running this magento with Php <strong>version 7.0.2</strong> &amp; <strong>Xampp version 7.0.20-0-VC14</strong>
  Whether it is an error of not having cron in my system or something else?
