title: Modify a key-value in a json using jq in-place
body: <p>I have a json in which I want to modify a particular value but the terminal always displays the json with the modified value but it does not actually change the value in the particular file. Sample json:</p>
  
  <pre><code>{
     name: 'abcd',
     age: 30,
     address: 'abc'
  }
  </code></pre>
  
  <p>I want to change the value of address in the file itself but so far I've been unable to do so. I tried using:</p>
  
  <pre><code>jq '.address = "abcde"' test.json
  </code></pre>
  
  <p>but it didn't work. Any suggestions?</p>
