ping [参数] [主机名称或IP地址]
ping命令用来测试主机之间网络的连通性。执行ping指令会使用ICMP传输协议，发出要求回应的信息，若远端主机的网络功能没有问题，就会回应该信息，因而得知该主机运作正常。
ping 命令每秒发送一个数据报并且为每个接收到的响应打印一行输出。ping 命令计算信号往返时间和（信息）包丢失情况的统计信息，并且在完成之后显示一个简要总结。
| 参数 | 说明 |
|---|---|
| -d | 使用Socket的SO_DEBUG功能 |
| -c <完成次数> | 设置完成要求回应的次数 |
| -f | 极限检测 |
| -i <间隔秒数> | 指定收发信息的间隔时间 |
| -l <网络界面> | 使用指定的网络界面送出数据包 |
| -l <前置载入> | 设置在送出要求信息之前，先行发出的数据包 |
| -n | 只输出数值 |
| -p | 设置填满数据包的范本样式 |
| -q | 不显示指令执行过程，开头和结尾的相关信息除外 |
| -r | 忽略普通的Routing Table，直接将数据包送到远端主机上 |
| -R | 记录路由过程 |
| -s <数据包大小> | 设置数据包的大小 |
| -t <存活时间> | 设置存活数值TTL的大小 |
| -v | 详细显示指令的执行过程 |
