title: ‘.”line”’ not accepted as valid syntax by jq - "unexpected INVALID_CHARACTER"
body: <p>I'm trying to make a GET request with curl in a bash file.
  So I call curl, and get a JSON response from my server, and I try to get the object <strong>line</strong> which is part of the response, and I do so with <strong>jq</strong>, so I can print the value. 
  But its not working.</p>
  
  <p>My response is something like this:</p>
  
  <pre><code>{"line":"Azul", "id":"j3453j45n35", "lat":"39.091937", "long":"-9.265441"}
  </code></pre>
  
  <p>My bash script:</p>
  
  <pre><code>#!/bin/bash
  while :
  do
      cmd=$(curl -i -H "Content-Type: application/json" http://localhost:8080/cards/exists/1 | jq ‘.”line”’) 
      sleep 2
  done
  </code></pre>
  
  <p>The result:</p>
  
  <blockquote>
    <p>jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Unix shell quoting issues?) at , line 1:
    ‘.”line”’
    jq: 1 compile error
    (23) Failed writing body</p>
  </blockquote>
  
  <p>Whats going wrong?
  I followed plenty of responses people advised online, but I keep getting the same response.
  My json object seems to be correct.
  I'm running this file on MacOS Sierra</p>
