As the first answer suggested, your best bet is to make sure you store the file name at the same time you open the filehandle.

Failing that, this works on Linux, but is very non-portable:

open my $fh, '/etc/motd';
my $fd = fileno($fh);
print readlink("/proc/$$/fd/$fd");

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
