求教grep问题

用grep如何处理这种问题

100 packets transmitted, 100 received, 0% packet loss,

100 packets transmitted, 100 received, 0% packet loss,  

100 packets transmitted, 100 received, 0% packet loss,

比如用grep取了三行数值

怎么能让他自动合成一行

就是变成

300 packets transmitted, 这样，然后丢包率也变成1个总的

丢包率

这不是grep能实现的～

awk 或 perl

如


perl -e 'while (<>) { m/^\s*(\d+)\D+(\d+)/; $sum += $1; $lost += $2; } print "$sum packets transmitted, $lost received, ". (100 - $lost*100/$sum) ."% packet loss,\n"if ($sum);'
