title: How do I get the full path to a Perl script that is executing?
body: <p>I have Perl script and need to determine the full path and filename of the script during execution. I discovered that depending on how you call the script <code>$0</code> varies and sometimes contains the <code>fullpath+filename</code> and sometimes just <code>filename</code>. Because the working directory can vary as well I can't think of a way to reliably get the <code>fullpath+filename</code> of the script.</p>
  
  <p>Anyone got a solution?</p>
