title: Using perl's `system`
body: <p>I would like to run some command (e.g. <code>command</code>) using perl's <code>system()</code>. Suppose <code>command</code> is run from the shell like this:</p>
  
  <pre><code>command --arg1=arg1 --arg2=arg2 -arg3 -arg4
  </code></pre>
  
  <p>How do I use <code>system()</code> to run <code>command</code> with these arguments?</p>
