using wireshark to view network traffic

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.
