How can I exec shell scripts from within a Gatling simulation?
<p>I want to add a scenario that runs in parallel to my main http-based scenarios to introduce errors into the environment (by deleting application instances etc.)</p>

<p>I can't see a way to do this from Gatling.  What I want is something that looks a little like this:</p>

<pre><code>exec({
  "chaos.sh" !
}).pause(10)
.exec({
  "firewallService.sh enable" !
})
</code></pre>

<p>etc.</p>

<p>Is this possible with Gatling?</p>
