title: What is the correct syntax for jq?
body: <p>Is there a commandline documentation to use <code>jq</code>? I am currently running this command:</p>
  
  <pre><code>%jq% -f JSON.txt -r ".sm_api_content"
  </code></pre>
  
  <p>It is supposed to read from <code>JSON.txt</code> and to output the value of <code>sm_api_content</code> (which is a string).</p>
  
  <p>But I am getting this error:</p>
  
  <pre><code>jq: error: Could not open file .sm_api_content: No such file or directory
  </code></pre>
  
  <p>Can anyone help me out here?</p>
