the =~ operator works on a scalar, not an array. You'll have to wait for Perl 6 to do
that :-).

Here's another way to do the same (warning, I didn't syntax check the code).
open FILE, $dirvalue or die "Can't open $dirvalue: $!";
my $found_date = 0;
while(<FILE>) {
print; # This print $_ which is the current line
$found_date = 1 if /Date:/; # the // is applied to $_ by default
}
close FILE or die "Can't close $dirvalue: $!";
print "OK\n" if $found_date;
Hope this helps
