内容如下:
vim liuliang.sh- #!/bin/bash
- while [ "1" ]
- do
- eth=eth1
- RXpre=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $2}')
- TXpre=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $10}')
- #echo $RXpre
- #echo $TXpre
- sleep 1
- RXnext=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $2}')
- TXnext=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $10}')
- #echo $RXnext
- #echo $TXnext
- clear
- echo -e "\t RX `date +%k:%M:%S` TX"
- RX=$((${RXnext}-${RXpre}))
- TX=$((${TXnext}-${TXpre}))
- if [[ $RX -lt 1024 ]];then
- RX="${RX}B/s"
- elif [[ $RX -gt 1048576 ]];then
- RX=$(echo $RX | awk '{print $1/1048576 "MB/s"}')
- else
- RX=$(echo $RX | awk '{print $1/1024 "KB/s"}')
- fi
- if [[ $TX -lt 1024 ]];then
- TX="${TX}B/s"
- elif [[ $TX -gt 1048576 ]];then
- TX=$(echo $TX | awk '{print $1/1048576 "MB/s"}')
- else
- TX=$(echo $TX | awk '{print $1/1024 "KB/s"}')
- fi
- echo -e "$eth \t $RX $TX "
- done
