title: Concat numbers from JSON without doublequotes using jq
body: <p>I have files with 1 json document per row and the fields <code>start_id</code> and <code>end_id</code> in each document. I'd like to use jq to extract these and print them on the same row.</p>
  
  <p>So far I have:</p>
  
  <pre><code>cat part* | jq '"\(.start_id) \(.end_id)"' | sed s/\"//g | head
  </code></pre>
  
  <p>This works, but I need the <code>sed</code> to remove the double quotes.</p>
  
  <p>In order to improve my jq-foo, is there a way to do this <em>without using sed</em>?</p>
  
  <p>e.g. given</p>
  
  <pre><code>{"start_id":1,"end_id":50}
  {"start_id":50,"end_id":99}
  {"start_id":99,"end_id":12}
  </code></pre>
  
  <p>get</p>
  
  <pre><code>1 50
  50 99
  99 12
  </code></pre>
  
  <p>instead of </p>
  
  <pre><code>"1 50"
  "50 99"
  "99 12"
  </code></pre>
