前言

当前业务，需要写一个脚本，不断监视com.android.phone 进程是否异常死掉

脚本

#!/system/bin/sh
last_pid=""
current_pid=""
while(true){
	current_pid=`ps -A | grep com.android.phone | awk '{print $2}'`
	if [ -n "$current_pid" ]; then

		if [ "$current_pid" != "$last_pid" ]; then  
			echo "PID changed from $last_pid to $current_pid"  
		fi  

		last_pid=$current_pid  
	else  
		echo "Failed to get PID for com.android.phone"  
	fi
	echo $current_pid
sleep 1
}

测试

// 获取phone pid并kill
kill -9 `pidof com.android.phone`
