title: Asynchronously running perl's backticks
body: <p>Right now I have a perl script that at a certain point, gathers and then processes the output of several bash commands, right now here is how I've done it:</p>
  
  <pre><code>if ($condition) {
    @output = `$bashcommand`;
    @output1 = `$bashcommand1`;
    @output2 = `$bashcommand2`;
    @output3 = `$bashcommand3`;
  }
  </code></pre>
  
  <p>The problem is, each of these commands take a fairly amount of time, therefore, I'd like to know  if I could run them all at the same time.</p>
