ifconfig,会有这样的输出:
RX bytes:1224128649 (1.1 GiB) TX
bytes:34114947 (32.5 MiB)
过一会再看,数值有所变化,两者的差值就是过去一段时间的流量。可是,这也太不人性
化了……
正所谓自己动手,丰衣足食,我们自己来写一个脚本,实时显示并刷新!
脚本如下,还是哪句话,本人功力有限,写脚
本的原则是够用就好。

$send_ra Bytes/sec Recv rate: $recv_ra Bytes/sec Total rate: $total_ra
Bytes/sec" echo "Total traffic after startup:
Send traffic: $sendn Recv traffic: $recvn"done该
脚本(假设名叫traffic)默认显示eth0的流量,如果你有多个网卡,请将网卡作为参数传进去,比如:
./traffic eth1
运
行结果如下:
