title: Should I escape shell arguments in Perl?
body: <p>When using <a href="http://perldoc.perl.org/functions/system.html" rel="noreferrer">system()</a> calls in Perl, do you have to escape the shell args, or is that done automatically?</p>
  
  <p>The arguments will be user input, so I want to make sure this isn't exploitable.</p>
