Hi monks Iam trying to solve an exercise from the textbook Intermediate Perl (8.6.2). the following data is stored in a file named data.

Gilligan: 1 coconut

Skipper: 3 coconuts

Gilligan: 1 banana

Ginger: 2 papayas

Professor: 3 coconuts

MaryAnn: 2 papayas

I have to create for each name a respective file such as this gilligan.info with its fruit written in the file . Like gilligan.info must have written in it : Gilligan: 1 coconut Gilligan: 1 banana. 

#my code:
#this fails since two Gilligan keys exist
use warnings;
use strict;
open( DATA, 'data' ) or die "i cannot read data:$!\n";
my %hash;

while (<DATA>) {
    my ( $name, $item ) = split(/:/);
    $hash{$name} = $item;

    for my $name ( keys %hash ) {
        my $lc_name = lc $name;

        open( FILE, ">$lc_name.info" ) or die "cannot open FILE:$!\n";
        print FILE "$name $hash{$name}";
    }
}

The trouble is that i shouldn't be using hash because there are 2 identical key entries(Gilligan). Now I've experimented with HoA with no luck some guidance is more than welcome

In reply to hash with identical keys by props
