in reply to Best way to get DD.MM.YY

Using Date::Simple you could do: 
use Date::Simple ('today');

my $today = today();
my $year  = $today->year;
my $month = $today->month;
my $day   = $today->day;

It's a few more lines, but you get the added benefit of having an object and its various methods. It's especially usefull if you're doing date calculations.

If you really wanted to fit it all on one line, you could. 
use Date::Simple ('today');

my $today = today()->month . '.' . today()->day . '.' . today()->year;

Using Time::Piece you could do: 
use Time::Piece;

my $t = localtime;
my $todays_date = $t->mdy('.');

or: 
use Time::Piece;

my $t = localtime;
my $todays_date = $t->strftime('%d.%m.%y');

Closer to what you are already doing, but you get the added benefit of using an object.

or (and ikegami's suggestion below to use %x): 
use Time::Piece;

my $t = localtime;
my $todays_date = $t->strftime('%x');
