title: How to run 2 commands at once in Jenkins with codeception and PhantomJS?
body: <p>I would like to create a jenkins job for running, my acceptance tests with codeception on phantomjs.</p>
  
  <p>So first I need to start the phantomjs headless server with</p>
  
  <pre><code>phantomjs --webdriver=4444
  </code></pre>
  
  <p>and now when this runs, I would run my tests with</p>
  
  <pre><code>php codecept.phar run acceptance
  </code></pre>
  
  <p>but when I define my jenkins job,
  I add a shell script for those commands</p>
  
  <p>BUT  when I run the first command: "phantomjs --webdriver=4444"
  so the bash is stuck while running the command... so I cant run the next command.</p>
