title: How can I convert a string to a file handle in perl?
body: <p>I have a very big-size string <code>$s="dfasdfasdfafd...."</code>, of nearly 1,000,000 characters. I want to convert it to a file handle, making it look like this string is read from a file. But I don't want to store it to a temp file and read it.</p>
  
  <p>Can anyone give me some suggestions?</p>
