title: cd to multiple directories in a shell script
body: <p>I am making a script named <code>Big_script.sh</code> to access two directories called <code>A</code> and <code>B</code>, inside them i need to access three directories called <code>A1</code>, <code>A2</code>, <code>A3</code>; <code>B1</code>, <code>B2</code>, <code>B3</code> (respectively). Once in there, i need the script to run another script with <code>sh small_script.sh</code>.</p>
  
  <p>Is it possible to do something like this in  <code>Big_script</code>:</p>
  
  <pre><code>cd */*
  sh small_script.sh
  </code></pre>
  
  <p>or is there any way to do that in a shell script or in python that could help? because it is not working</p>
