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" ]; thenif [ "$current_pid" != "$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"  fiecho $current_pid
sleep 1
}

测试

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