Linux下统计高速网络中的流量

netpps.sh统计每秒数据量，包含接收（RX）或发送（TX）

netpps.sh eth0

#!/bin/bash

INTERVAL=""  # update interval in seconds

if [ -z "$1" ]; then
        echo
        echo usage: $ [network-interface]
        echo
        echo e.g. $ eth0
        echo
        echo shows packets-per-second
        exit
fi

IF=$

while true
do
        R1=`cat /sys/class/net/$/statistics/rx_packets`
        T1=`cat /sys/class/net/$/statistics/tx_packets`
        sleep $INTERVAL
        R2=`cat /sys/class/net/$/statistics/rx_packets`
        T2=`cat /sys/class/net/$/statistics/tx_packets`
        TXPPS=`expr $T2 - $T1`
        RXPPS=`expr $R2 - $R1`
        echo "TX $1: $TXPPS pkts/s RX $1: $RXPPS pkts/s"
