检查输出中添加“stderr=STDOUT”没有产生任何有用的反馈

如何获取有关错误的更多信息，以便对其进行故障排除？
正如您的错误消息所述，ping在非零退出状态下完成。这可能意味着，例如，提供的IP地址无法访问，或者您输入了错误的参数

从
ping
手册页（）：

如果ping根本没有收到任何回复数据包，它将以代码1退出。如果同时指定了数据包计数和截止日期，并且截止日期到达时收到的数据包少于计数，则它也将以代码1退出。在另一个错误中，它以代码2退出。否则它将以代码0退出。这使得可以使用退出代码查看主机是否处于活动状态

您可以尝试捕获
调用的进程错误
，并查看它在
输出中包含的内容。

引发的非零退出代码，如果出现错误（例如未知域名，或站点已关闭，或站点因某种原因被ICMP阻止，或您的Internet连接已关闭），
ping
将返回非零退出代码

如果要同时检查输出代码和退出代码，请使用：
