您正在寻找 Process.spawn。用法是这样的：
You're looking for Process.spawn. The usage would be something like this:
您似乎只是想通过打开浏览器来“ping”http://www.google.com，然后然后将其关闭。
有更快、更简单的方法可以做到这一点。在您的情况下，最简单的一种（因为您已经设置了命令行）是使用 curl 或 wget：
这将“ping”网站，并简单地丢弃输出。它会比创建 Firefox 实例快得多。
It seems that you are just trying to "ping" http://www.google.com by opening a browser and then closing it up.
There are faster, easier ways to do that. The simplest one in your case (since you already have a command line set up) would be using curl or wget:
This will "ping" the website, and simply discard the output. It'll be much faster than creating a firefox instance.
