I'm new to coding and perl and am stuck with a problem. I've looked in other threads and googled the problem but I haven't found a solution yet. Part of my concern is that I'd like to understand why it's not working rather than just getting a quick fix to the problem. I want this code to count the number of times that each string in an array appears in that array. So, as an example, if-

@array = qw('dog', 'cat', 'sheep', 'dog', 'dog', 'cat');

It would return

>dog, 3
>cat, 2
>sheep, 1

The code that I'm using is below. Currently, for any input, it only gives a count of "1" as the number of occurrences in the array. I know this to be false as I've created test arrays with multiple identical values. What am I doing wrong, Monks?

use strict;
use warnings;

my $i;
my $j;
my @data;

for my $file (@ARGV) {

open (RAW, "./$file") || die "Cannot open specified file to be process
+ed\n";

while(<RAW>) {

        @data = join('', $_ =~ /^(\d\d\d\d)-(\d\d)-(\d\d) (\d+):(\d+):
+(\d+)/);

for $i (@data) {
        my $cnt = 0;
for $j (@data){
        if ($i eq $j) {
                $cnt = $cnt + 1;
                print "$i, $j, $cnt\n";
                                }
                        }
                }
        }
}
