title: Extract data from JSON file using bash
body: <p>Let's say that we have this kind of JSON file:</p>
  
  <pre><code>{
    ... 
    "quotes":{
       "SOMETHING":10,
       ...
       "SOMETHING_ELSE":120.4,
       ...
    }   }
  </code></pre>
  
  <p>How can I obtain those values and use them in order to add them together?</p>
  
  <p>Am I able to do even this?</p>
  
  <pre><code>#!/bin/bash
  
  #code ...
  
  echo "$SOMETHING + $SOMETHING_ELSE" | bc
  
  #code ...
  
  #exit
  </code></pre>
  
  <p>I will obtain the JSON file with wget command. All I want is the content from this file.</p>
  
  <p>Can you help me, please? I am a beginner in shell programming.</p>
