title: changing current directory from a child process
body: <p>I wrote a script that changes current directory.</p>
  
  <pre><code>#!/bin/sh
  cd userA/toWhere/
  </code></pre>
  
  <p>When the script is sourced, it changes the current directory but I want to change it from child process by using <code>bash invocation</code>. Is it possible?</p>
