title: How to set correct perl path
body: <p>I have 2 versions of perl installed. perl v5.18.2 and v5.20.0 . But when I do <code>perl -v</code> I get perl v5.18.2.  I don't need v5.18.2 at all. I need v5.20.0. How do I change the path to include v5.20.0 and not v5.18.2?</p>
  
  <p>Here is my <code>$PATH</code>:</p>
  
  <pre><code>/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
  </code></pre>
  
  <p>v5.18.2 is installed at <code>/usr/bin/perl</code> and <code>/usr/bin/perl5.18.2</code>, and v5.20.0 at <code>/root/perl5/perlbrew/perls/perl-5.20.0/bin/perl</code>.</p>
