title: How do I remove all keys except one with jq?
body: <p>Given a list of objects, with many keys I don't want:</p>
  
  <pre><code>[{
      "name": "Alice",
      "group": "Admins",
      "created": "2014"
  }, {
      "name": "Bob",
      "group": "Users",
      "created": "2014"
  }]
  </code></pre>
  
  <p>How do I filter these objects to only include keys I want?</p>
  
  <pre><code>[{
      "name": "Alice"
  }, {
      "name": "Bob"
  }]
  </code></pre>
  
  <p>I've tried <code>jq '.[].name'</code> but that extracts the values, rather than preserving the objects.</p>
