Answer 2

在上下文xml中添加这些并将其添加到类路径中。在属性文件中添加相应的属性。

#!/bin/bash

old_packets=0

while true; do
    packets=$(awk '$1 == "eth0:"{print $3}' /proc/net/dev)
    if ((old_packets)); then
        clear
        echo "$(bc <<< "($packets - $old_packets) / 10") packets/seconds"
    fi
    old_packets=$packets
    sleep 10
done
