    The script includes a print statement for this purpose. The print statement prints the contents of $link correctly, but system("echo", $link) only prints w. If you download the sample file I included and put it in the same directory of the script you can see the result yourself.

      Excuse me, I've overlooked that line.

      What is your OS? What shows 'which echo' on your system?

      This code works pretty well on my system:

      #!/usr/bin/env perl use strict; use warnings; use 5.010; my $url = '""'; system('echo', $url); $url = ""; system('echo', $url);
