Multiple commands in Symfony Process Component

I’m trying to execute multiple commands using Symfony Process Component but second command is not being processed. What am I doing wrong?

        $process = new Process('sshpass -p password ssh user@host');
        $process->run();
        if (!$process->isSuccessful()) {
            throw new ProcessFailedException($process);
        }
        echo $process->getOutput();

        $process1 = new Process("sudo reboot -f");
        $process1->run();
        if (!$process1->isSuccessful()) {
            throw new ProcessFailedException($process1);
        }
        echo $process1->getOutput();

Answer

Process are isolated, the second will not be executed inside the ssh session you open at the top of your code.

You must use only one process todo that.
