in reply to Append to hash reference

use Data::Dumper; my $ref1 = { foo => 1, bar => 2 }; my $ref2 = { baz => 3, quux => 4 }; # Assign to the ref1 hash the data in both hashes %$ref1 = (%$ref1, %$ref2); print Dumper $ref1;

Or...

use Data::Dumper; my $ref1 = { foo => 1, bar => 2 }; my $ref2 = { baz => 3, quux => 4 }; # Loop through the keys of the second hash, assigning values into the +first $ref1->{$_} = $ref2->{$_} for keys %$ref2; print Dumper $ref1;

[Corion]: choroba: Yeah, that's a lot of "fun" for one week...
[Corion]: I guess I should stage some product photos for Sane Dots Supplies ;)
[marto]: I had some ideas about that Corion
[marto]: I'll send a message over the weekend maybe :P
[Corion]: choroba: I avoided the "fun" of emergency shopping for a new flat iron by trying the flat iron without the timer that sat between it and the mains power. Seems as if just the timer is broken.

Corion munches on the traditional German winter fruit, strawberries. Imported from Spain at the price of EUR 0.77 per 150g - not really cheap but surprisingly good for a winter produce
