title: How can I run multiple curl requests processed sequentially?
body: <p>Assuming I'm a big Unix rookie:</p>
  <ul>
  <li><p>I'm running a curl request through <a href="https://en.wikipedia.org/wiki/Cron" rel="noreferrer">cron</a> every 15 minutes.</p>
  </li>
  <li><p>Curl basically is used to load a web page (PHP) that given some arguments, acts as a script like:</p>
  <pre><code>curl http://example.com/?update_=1
  </code></pre>
  </li>
  </ul>
  <p>What I would like to achieve is to run another &quot;script&quot; using this curl technique,</p>
  <ul>
  <li>every time the other script is run</li>
  <li>before the other script is run</li>
  </ul>
  <p>I have read that curl accepts multiple URLs in one command, but I'm unsure if this would process the URLs sequentially or in &quot;parallel&quot;.</p>
