I think you introduced unneeded complexity here.
Off the top of my head:
use File::Find;
my ($search, $ext) = @ARGV;
$ext = ".$ext" if defined $ext;
@ARGV = ();
find sub { push @ARGV, $_ if -f and not $ext or /\Q$ext$/ }, ".";
while (<>) {
close ARGV if eof;
print "$ARGV: $. :$_\n" if /$search/;
}
There's a few optimizations with
qr// if you're really into speed,
but this should handle 90% of it.
