title: Parse JSON file in linux using jq
body: <p>I have a json file, call it x.json satisfying this schema:</p>
  
  <pre><code> }
        },
        "type": "persons"
      },
      "person's in a group": {
        "primary": {
          "attributes": {
            "firstname": "sara",
            "lastname": "jones",
            "age": "32",
            "weight": "130",
  </code></pre>
  
  <p>to get the list of first name, I have to write:</p>
  
  <pre><code>cat x.json | jq '.title[].type[].properties.firstname'
  </code></pre>
  
  <p>is there a shorter way to get the first name? Instead of having to write the whole line of objects? 
  Also is there a way to list more than just the first name, for example first and last name? 
  lastly, any idea how I can import this out into a CVS file or any other flat file system? </p>
