推荐答案

一个 hack 是(误)使用 ping 命令:

One hack is to (mis)use the ping command:

ping 127.0.0.1 -n 6 > nul

说明:

• ping 是一个发送 ping 请求的系统实用程序.ping 适用于所有版本的 Windows.
• 127.0.0.1 是 localhost 的 IP 地址.此 IP 地址可保证始终解析、可访问并立即响应 ping.
• -n 6 指定有 6 个 ping.每次 ping 之间有 1 秒的延迟，因此对于 5 秒的延迟，您需要发送 6 次 ping.
• <代码>>nul 抑制 ping 的输出，通过 重定向 到 nul.

• ping is a system utility that sends ping requests. ping is available on all versions of Windows.
• 127.0.0.1 is the IP address of localhost. This IP address is guaranteed to always resolve, be reachable, and immediately respond to pings.
• -n 6 specifies that there are to be 6 pings. There is a 1s delay between each ping, so for a 5s delay you need to send 6 pings.
• > nul suppress the output of ping, by redirecting it to nul.
