Good day. I have a script that uses WWW::Mechanize to download PDFs from a website. It works for downloading, but I need to save each file with a file name derived from the link that it came from.

Here is the code:

use URI::Escape;
 
  
 my $start = "http://www.xxxx.com/programs_results/";
           my $mech = WWW::Mechanize->new( autocheck => 1 );
           $mech->get( $start );
           my @links = $mech->find_all_links( url_regex =>
           qr/\d+.+\.pdf$/ );   
             
           chdir $progdest or die "Can't change
           directory: $!\n";
          
           for my $link ( @links ) {
           my $url = $link->url_abs;
           my $filename = URI::Escape::uri_escape( $link-
           >url_abs->path );
           $filename =~ s[^.+/][];
           mech->get( $url, ':content_file' => $filename );
           }

This code(listed above) works, but I need to make a change. The PDFs are saving with the encoding in the file name. How could this be filtered so that the end result looks like A, not B?

A. 100004_20090326.pdf

B. %2Fpdf%2F100004%2F_20090326.pdf

Thanks alot!!!
