How to start script many times at same time

[xenion54]

On windows i can run script with same name multiple times (with different params). On linux, this doesn't work. After start first script, others scripts not starting. Event onWorkerStart called just first time. How can i run same script multiple times in linux?

<?php

use Workerman\Connection\TcpConnection;

require_once dirname(__DIR__) . DIRECTORY_SEPARATOR . 'Libs' . DIRECTORY_SEPARATOR . 'init.php';

$args = getopt('', ['port:']);

global $argv;

$argv[1] = 'start';
$argv[2] = '-d';

$sw = new \Workerman\Worker('websocket://0.0.0.0:' . $args['port']);
$sw->count = 1;

$sw->onWorkerStart = function (\Workerman\Worker $worker) {
    echo $args['arg1'] . PHP_EOL; // this line called only once
};

\Workerman\Worker::runAll();
