title: Ubuntu 16.04: -sh: source: not found
body: <p>I updated my <code>.bashrc</code>. After that, when I tried <code>source ~/.bashrc</code> to make it works, I got:</p>
  
  <pre><code>-sh: 13: source: not found
  </code></pre>
  
  <p>I have reviewed the suggestions on <a href="https://stackoverflow.com/questions/13702425/source-command-not-found-in-sh-shell">source command not found in sh shell</a>. But I still don't understand how to solve my problem.</p>
  
  <p>If I use <code>. ~/.bashrc</code> alternatively, I will get:</p>
