How can I change the date formats in Perl?

Question

I just want to convert the dates from 20111230 format to 30-dec-2011.

Answer 1

One way is to use Date::Simple:

use warnings;
use strict;
use Date::Simple qw(d8);

my $d = d8('20111230');
print $d->format('%d-%b-%Y'), "\n";

__END__

30-Dec-2011
