Why bother wrestiling with complex regular expressions when someone
else has already done the work? Perl has a URI module ("yum install
perl-URI") which understands how URIs (and URLs) work. I'd recommend
using that.

  use URI;

  my $url = URI->new('http://somesite.org/somefile.zip');
  say $url->path; # prints "/somefile.zip"

Then there's the File::Basename module (included with the Perl
distribution) for dealing with file paths.

  use File::Basename;

  say basename($url->path); # prints somefile.zip

Perl programming gets a lot easier if you use the tools that are already there.

Cheers.
