A couple of points:
(1) In the foreach loop, $file contains a filename together with its path and extension. To extract just the name part, you need something like:
(my $basename = fileparse($file)) =~ s/ \. .* $ //x;
which uses the fileparse function from File::Basename to extract the filename, then removes the extension (if any).
(2) print Dumper(@matches); will print each match on a separate line. You would probably be better off with something like this:
printf "'%s' matches: %s\n", $basename, join(', ', @matches);
