use of a utility module List::MoreUtils allows you to write code, for your first question, that looks much like your specification. 
use strict;
use warnings;
use List::MoreUtils qw(any);
my @strings = qw(abcd abbd efgh);
print @strings if any {/(\w)\1/} @strings;

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
