title: Display progress with script running in paralel
body: <p>I have a bash script that runs in parallel inside a for loop, like this:</p>
  <pre class="lang-sh prettyprint-override"><code>for (( n=0; n&lt;${LIMIT}; n++ )); do
     my_function $n &amp;
  </code></pre>
  <p><code>my_function</code> is a function that runs in <code>LIMIT</code> virtual machines/nodes with ssh. It works fine, but i am not able to keep track of execution progress. It would be nice to have a progress bar or any other tool that can give a completion estimate. Unfortunately, all approaches i've searched doesn't apply to this parallel case.</p>
  <p>Thanks</p>
