I have a bunch of files in my directories that I need to mass rename. I'm trying to get a script to change filename extensions in a directory, my code runs but it doesn't do anything. Any help is appreciated!

#!/usr/bin/perl
use File::Basename qw(fileparse);
@ARGV == 3;

my $dir = $ARGV[0];
my $old = $ARGV[1];
my $new = $ARGV[2];

opendir(my $path, $dir);
my @list = readdir($path);

foreach(@list){
        my $name = fileparse("$_", ".$old");
        rename("$name.$old", "$name.$new");
};
