title: reading keys shell
body: <p>Now, I have done the following: </p>
  
  <pre><code>for row in $(echo "${values}" | jq -r '.[]'); do
      -jq() {
          echo ${row} | jq -r ${1}
      }
      echo $(_jq '.samplekey')
  done
  </code></pre>
  
  <p>Here, I am unable to figure out how to extract the keys without passing in the exact keyname. Please help me, thanks! </p>
