组装代码

以后有空再把它工程化吧, shell写的又不是不能用

# 自行配置
DeviceMAC="C1:0C:0A:02:XX:XX"
Interval=5

# 自定义操作
action(){
    echo "lock"
    # todo
    echo "Turn off my light"
    miiocli yeelight --ip 192.168.2.214 --token xxxxxxxxxxxxxxxx off
    echo "Lock my Mac Book Pro"
    ssh MacBook-Pro pmset displaysleepnow
}

export last_status=""
while true ; do
    status=$(bluetoothctl info $DeviceMAC | grep 'Connected:' | awk -F': ' '{ print $2}')
    if [ "$status" == "no" ];then
				if [ "$last_status" == "yes" ];then
						 action
				fi
		elif [ "$status" == "yes" ];then
				echo "yes"
    fi
	last_status=$status
    sleep $Interval
done
