title: Percent sign % not working in crontab
body: <p>I have a cron issue with <code>curl</code>:</p>
  
  <pre><code>curl -w "%{time_total}\n" -o /dev/null -s http://myurl.com &gt;&gt; ~/log
  </code></pre>
  
  <p>works great and add a line in log file with total_time.</p>
  
  <p>But the same line with cron doesn't do anything.</p>
  
  <p>It's not a path problem because <code>curl http://myurl.com &gt;&gt; ~/log</code> works.</p>
