Question

我写了一个小脚本来从我的ubuntu机器读取syslog中的NetworkManager数据。 但输出文件似乎是空的，我看不出我做错了什么。一些帮助将非常感激。

提前致谢：

代码：

#!/usr/bin/python

import os
import os.path


o = open("/home/user/Desktop/Python/log.txt", "w") #yourdestinationfolder

if os.path.exists("/var/log/messages"):  #messages in ubuntu is no more
    f = open("/var/log/messages", "r")

    for line in f.readlines():

            if "NetworkManager" in line:
                    o.write(line)


if os.path.exists("var/log/syslog"):
    d = open("/var/log/syslog" , "r") 

    for line in d.readline():

        if "NetworkManager" in line:
                    o.write(line)
