My question is what is the meaning of -arp since it is not in the command prompt documentation?

What I have tried:

推荐答案

ping命令非常厚，他们没有投入大量精力它的参数解析。

如果查看命令行参数列表： Ping命令（示例，选项） ，开关等） [ ^ ]您会注意到它们都是单字符开关： - x其中x是单个字符。

忽略该字符右侧的任何内容，因此您的rp为j是的垃圾，忽略它。

尝试一下，这就像-a一样：

The ping command is a pretty thick one, they didn't put a lot of work into its parameter parsing.
If you look at the command line argument list: Ping Command (Examples, Options, Switches, and More)[^] you will notice they are all single character switches: "-x" where "x" is a single character.
Anything to the right of that character is ignored, so your "rp" is just junk, ignore it.
Try it, this works like -a as well:

ping -a?"Hello world" google.com

没有任何意义，因为当第一个是已知选项时，Windows ping 命令会忽略任何其他字符。



您可以通过需要额外参数的选项来检查：

There is no meaning because the Windows ping command just ignores any additional characters when the first is a known option.

You can check this with options requiring an additional parameter:

ping -n 2 dest
ping -n1 2 dest

两者都将执行相同的操作（发送两个请求）和

Both will perform the same action (send two requests) and

ping -n1 dest

打印错误消息。



这与典型的Unix命令行实用程序不同，后者可以连接多个选项，并且选项参数可以与命令一起传递。

prints an error message.

This differs from typical Unix command line utilities where multiple options can be concatenated and option parameters can be passed together with the command.
