Two-segment shell script that counts network card traffic (using ifconfig) _linux shell

Use shell script to compute the Linux NIC traffic, the most critical point in the method:

Copy Code code as follows:

Ifconfig $eth _name | grep bytes | awk ' {print $} ' | Awk-f: ' {print $} '

The flow of input and output is obtained by Ifconfig eth0|grep bytes.

Copy Code code as follows:

/@rac2 =>dd2$ifconfig Eth0|grep bytes
RX bytes:1638005313300 (1.4 TiB) TX bytes:3408060482049 (3.0 TiB)

The results are then used to derive the desired field value from awk.
Fixed time to get these values, in the Write a loop calculation can get the network card traffic.

Code One:

#!/bin/bash #

# date:2013/2/26

date
rm-rf/tmp/ifconfig_ Log while
(($n >= 0))
do
 n=$ (($n-1));
 Date >>/tmp/ifconfig_log
 ifconfig eth1 >>/tmp/ifconfig_log sleep

done
 
grep "RX Bytes: "/tmp/ifconfig_log | Awk-f "[: |]" ' {print $} ' | awk ' Begin{tmp=$1}{if (FNR > 1) Print $1-tmp}{tmp=$1} '
