title: Groovy slash operator (Jenkins job-dsl)
body: <p>We would like to understand a couple of legacy job-dsl scripts but don't know what "slash operator" means in this context (as it cant be division):</p>
  
  <pre><code>def command = (shells.first() / command)
  </code></pre>
  
  <p>We have tried to look it up in several Groovy books but only found the trivial solution that it means 'division'. </p>
