title: How to search in json with jq?
body: <p>How can I output just the <code>duration</code> values from below?</p>
  
  <p>If I search for <code>jq -r ".media.duration"</code> then I get <code>nil</code>.</p>
  
  <pre><code>$ cat test.json | jq -r ".episodes[1:]" 
  [
    {
      "uniqueHash": "a2dc48cd0f9",
      "startOffset": "{0}",
      "media": {
        "720p": {
          "extension": "mp4",
          "filesize": "1702",
          "duration": "00:51:55",
        },
      }
    },
    {
      "uniqueHash": "a2d0f9",
      "startOffset": "{0}",
      "media": {
        "720p": {
          "extension": "mp4",
          "filesize": "12602",
