I assume the filenames you are interested in are in the following format:

name.extension

That is, I am going to require that the extension of

..bashrc

is blank.

We are interested in the string following the last period in the name:

#! /usr/bin/perl

use strict;
use warnings;

my @list = qw(name name.extension .extension);

for (@list) {
my ($ext) = /.+\.(\w+)?$/;
defined $ext or $ext = '';

print "Name: $_\tExtension: $ext\n";
}

__END__

Also, look into File::Basename::fileparse
