Fellow Monks.

I have a created hash key and want to count the number of each names present. I have already created the hash. The problem I am having is extracting the counts.

Example Data

AAA

AAA

ABC

ACC

ACB

Below is my code.

my %name;
open(FILE, $ARGV[0]) or die "Cannot open the file: $!";

my $hashkey;
my $hashvalue;
while (my $line = <FILE>) {
    if ($line =~ /(\S+)/) {
        $hashkey = $1;
        $hashvalue = $line;
        $name{$hashkey} = $hashvalue;
        $name{$hashkey}++;
    }
    elsif ($line =~ /\S/) {
        chomp $line;
    }
}
foreach my $hashname (keys %name) {
    print "$_ $name{$_}\n" for keys %name;
}    
    
close FILE;
exit;

pseudo code

if $hashname exists

count{}++

Desired Output

AAA 2

ABC 1

ACC 1

ACB 1
