Dear Monks

When I print data with my code, I get unexpected results

I stock data in a hash table :

when I try to print my hash table, and make a loop on the keys, instead of seeing all the elements that were pushed in the hash, I see only one per key

Could you tell me why please ?

Here is my code 

#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;
use Cwd;



# input files to work on 
my $file= "$ARGV[0]"; 
open INFILE, '<', $file, or die "Can't open $file : $!";


my %aircraftID;


while (my $line = <INFILE>){

    chomp($line);
    my @Elements = split ';', $line;

    
    # the command shift takes away the first element of the table and 
+stocks it in a variable
    my $aircraft_id = shift(@Elements);
    # the element of the first column (the aircraft_id) has been taken
+ from Elements
    
    # a hash table cannot contain lists
    # that's why a reference to a list is needed
    # this reference is called by the antislash \ 

    
    my $row = \@Elements;
    push @{$aircraftID{$aircraft_id}}, @{$row};
    print STDOUT "la row2 vaut @{$row}\n";
    
}
close INFILE;

print STDOUT "\n";
foreach my $cle (keys %aircraftID){
 print STDOUT "the value of $cle is : \n";
print STDOUT  "@{$aircraftID{$cle}}\n";
 }
