title: Perl: suppress output of backtick when file not found
body: <p>In my code :</p>
  
  <pre><code>$status = `ls -l error*`;
  </code></pre>
  
  <p>It shows output : <code>ls *error No such file or directory.</code> 
  How can I suppress this message. I am interested in determining that the error files are generated or not. If yes, I need the list of files else ignore (without printing the message)</p>
