title: Command to replace string in a file
body: <p>I want to replace a string in a file using command, but the thing is the string is such</p>
  
  <pre><code>"https": false,
  </code></pre>
  
  <p>I want to change it to </p>
  
  <blockquote>
    <p>"https": true,</p>
  </blockquote>
  
  <p>and vice versa.</p>
  
  <p>is there any way to accomplish this thru command?
  Am developing auto script so whenever a user logins this command kicks in, I have sorted everything except this.</p>
