Welcome to the monastery. Here was a quick test snippet that appears to give results similar to those you seek:

my $fn = shift @ARGS;
@lines = (); 
open my $df, $fn or die $!; 
while ( $l = <$df> ) { 
    chomp $l; unshift @lines, $l; 
} 
close $df; 
foreach my $l ( map{ $_ = reverse $_; $_; } @lines ) {
    print reverse $l, "\n"; 
}

Hope that helps.
