获取所有网卡名称

interfaces=$(ifconfig -s | awk '{print $1}' | grep -v Iface)

for interface in $interfaces do

获取该网卡的进出流量

rx=$(ifconfig $interface | grep "RX packets" | awk '{print $5}') tx=$(ifconfig $interface | grep "TX packets" | awk '{print $5}')

统计总流量

total_rx=$(($total_rx + $rx)) total_tx=$(($total_tx + $tx)) done

echo "总入流量：$total_rx bytes" echo "总出流量：$total_tx bytes"
