openWrt中實時查看無線客戶端連接狀態

主要思路：

1.通過iwinfo無線信息的命令，獲取當前已經連接的無線客戶端信息； 
2.通過for命令獲取目標設備的MAC地址；

#/bin/sh
#pl=$(iwinfo wlan0 assoclist)
i=1
while i=1
do
        pl=$(iwinfo wlan0 assoclist)
        for line in $pl
        do
                if [ $line = "38:*:1A:*:8E:*" ]
                then
                        echo "found!"
                        exit 0
                else
                        echo "no found!" >/tmp/found_devices
                        sleep 1
                fi
        done
done
