Unix Awk环路|多条线路

我需要一些帮助，使用循环和Awk命令。我需要过滤ping测试脚本的输出，结果是：

--- hostname1 ping statistics ---
15 packets transmitted, 14 packets received, 6% packet loss
--- hostname2 ping statistics ---
15 packets transmitted, 15 packets received, 0% packet loss
--- hostname3 ping statistics ---
15 packets transmitted, 15 packets received, 0% packet loss
--- hostname3 ping statistics ---
15 packets transmitted, 2 packets received, 86% packet loss

。。。我需要的是一个类似于循环和awk的过滤器：

第1行->awk'{print$（NF-3）}'->主机名1

第2行->awk'{print$（NF-2）}'->这里我还需要%数字的切分，如果可能的话，试试这个：

[ping command here] | awk '/^---/ {printf("%s ", $2)} /%/ { print $7} {next}'

：哦，这帮我解决了很多grep和awk的问题，你说了算！谢谢。
