title: Escaping characters in a Jenkins build
body: <p>I am trying to escape the '@' in the below code for a Jenkins build:</p>
  
  <pre><code>            sh "curl --dH "@$Tom" http://google.com"
  </code></pre>
  
  <p>How do I escape it?</p>
  
  <p><strong>Edit</strong>: If I use a \ in front of the @ as displayed below:</p>
  
  <pre><code>            sh "curl --dH "\@$Tom" http://google.com"
  </code></pre>
  
  <p>I get another error, stating unexpected character "\". </p>
