you also quoted the whole regex in '' but included the // which are the
normal regex delimiters. remove the outer quotes.
and use the qr// form for regexes.
and you don't want the + after the \d as the {5,} is the count. you
can't have both types of repeat counts.
my $re = qr/^\d{5,}/ ;
that should be all you need.
read perlretut to learn more regex basics. you have escaping and quoting
mistakes in the original.
