title: Stress testing a command-line application
body: <p>I have a command line perl script that I want to stress test. Basically what I want to do is to run multiple instances of the same script in parallel so that I can figure out at what point our machine becomes unresponsive.</p>
  
  <p>Currently I am doing something like this:</p>
  
  <pre><code>$ prog &gt; output1.txt 2&gt;err1.txt &amp; \
    prog &gt; output2.txt 2&gt;err2.txt &amp;
    . 
    .
    .
    .
  </code></pre>
  
  <p>and then I am checking ps to see which instances finished and which didn't. Is there any open-source application available that can automated this process? Preferably with a web-interface?</p>
