Ⅰ 批处理的ping 命令怎么用
因为PING一个包大概要1秒呀，所以就用来作延时了，虽然这个方法笨死了。
ping www.163.com 这样，就是拼网易的主页，默认会拼四个包。
ping 127.1 就是拼本机了
加 /n 就是指定拼的包的个数。如
ping /n 5 127.1
这就是拼5个包，就不是默认的四个了。这样就大延时5秒吧。其实这要看网卡了。还有网络状态。一点都不准。
ping /n 5 127.1 >nul 就是把拼的输出信息屏蔽，也就是屏幕上不显示拼的结果，反正我们要延时，不是想知道拼的结果。
ping 本来就作用是来测试网络是否通畅的。如果你拼 163,拼不通，就说明你上不了网易的网站了。
以下是参考：
