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.
