这个看门狗抓进程id的，这进程没在跑，运行看门狗他还在输出变的id

奇怪了


看门狗脚本程序

import os     #基于python2
import sys
import commands
import time
from  subprocess import check_output

shellcmd = "pgrep -f live.py"
while True:
    print("start check process:",shellcmd);
    try:
        time.sleep(1)
        pid = commands.getoutput(shellcmd)
        print(pid)
        if pid.find("\r")==True:
            print("live.py run state is normal")
        else:
            print "the live.py process have exited."
    except:
        print("unknow error:{0}".format(sys.exc_info()))
        break

开启live.py这个进程之后 再运行watch_dog打印换行，但是我的代码里没有换行符号啊
