title: How to switch to bash shell from some other shell?
body: <p>I am running a shell script "envsetup.sh" and I keep getting the following error.</p>
  
  <pre><code>Badly placed ()'s
  </code></pre>
  
  <p>I found out the error is because I am not in a bash shell environment.  Can anyone help explain how to enter the <code>bash</code> shell environment?</p>
