在网上看到这个单机流量的脚本,挺不错的。
复制代码 代码如下:
#!/bin/sh
usage(){
echo “Usage: $0 [-i INTERFACE] [-s INTERVAL] [-c COUNT]”
echo
echo “-i INTERFACE”
echo “ The interface to monitor, default is eth0.”
echo “-s INTERVAL”
echo “ The time to wait in seconds between measurements, default is 3 seconds.”
echo “-c COUNT”
echo “ The number of times to measure, default is 10 times.”
exit 3
}
readargs(){
while [ "$#" -gt 0 ] ; do
case “$1″ in
-i)
if [ "$2" ] ; then
interface=”$2″
shift ; shift
else
echo “Missing a value for $1.”
echo
shift
usage
fi
;;
-s)
if [ "$2" ] ; then
sleep=”$2″
shift ; shift
else
echo “Missing a value for $1.”
echo
shift
usage
fi
;;
-c)
if [ "$2" ] ; then
counter=”$2″
shift ; shift
else
echo “Missing a value for $1.”
echo
shift
usage
fi
;;
*)
echo “Unknown option $1.”
echo
shift
usage
;;
esac
done
}
checkargs(){
if [ ! "$interface" ] ; then
interface=”eth0″
fi
if [ ! "$sleep" ] ; then
sleep=”3″
fi
if [ ! "$counter" ] ; then
counter=”10″
fi
}
printrxbytes(){
/sbin/ifconfig “$interface” | grep “RX bytes” | cut -d: -f2 | awk ‘{ print $1 }'
}
printtxbytes(){
/sbin/ifconfig “$interface” | grep “TX bytes” | cut -d: -f3 | awk ‘{ print $1 }'
}
bytestohumanreadable(){
multiplier=”0″
number=”$1″
while [ "$number" -ge 1024 ] ; do
multiplier=$(($multiplier+1))
number=$(($number/1024))
done
case “$multiplier” in
1)
echo “$number Kb”
;;
2)
echo “$number Mb”
;;
3)
echo “$number Gb”
;;
4)
echo “$number Tb”
;;
*)
echo “$1 b”
;;
esac
}
printresults(){
while [ "$counter" -ge 0 ] ; do
counter=$(($counter – 1))
if [ "$rxbytes" ] ; then
oldrxbytes=”$rxbytes”
oldtxbytes=”$txbytes”
fi
rxbytes=$(printrxbytes)

if [ "$oldrxbytes" -a "$rxbytes" -a "$oldtxbytes" -a "$txbytes" ] ; then
echo “$(/bin/date +%Y%m%d-%H%M%S) RXbytes = $(bytestohumanreadable $(($rxbytes – $oldrxbytes))) TXbytes = $(bytestohumanreadable $(($txbytes – $oldtxbytes)))”
else
echo “Monitoring $interface every $sleep seconds. (RXbyte total = $(bytestohumanreadable $rxbytes) TXbytes total = $(bytestohumanreadable $txbytes))”
fi
sleep “$sleep”
done
}
readargs “$@”
checkargs
printresults
测试如下:
每三秒的流量,总输出999行,可以输出到文件里,其中:前面为时间,Rx Packets 是接收数据包,即下载,Tx Packets 是发送数据包,即上传.
复制代码 代码如下:

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
