hi all,

how to write a bash script that retrieves statistics from netstat, displays the number of packets incoming per second and then convert the number of packets to bytes/bits and display that as well?

Bash scripting is like using the console... what might be useful to you are gawk, head and tail to display the right information from netstat. You can also do math in bash scripting, to convert the bytes to bits and vice versa (8 bits per byte..)

This might be of some use: http://www.tldp.org/LDP/abs/html/index.html or simply the main site http://www.tldp.org/guides.html

You might also want to search http://freshmeat.net and http://sourceforge.net for scripts that might have already been written.

I think you wanted the total pkts received ( ? ) If so, here's the first part...

Code:

#!/bin/bash

for i in `netstat |grep '[0-9]'|awk '{print$2}'`;do
a=$(($a + $i ))
done
echo Total received pkts is $a
