在Python中监视进程? [英] Monitor Process in Python?

问题描述

我认为这是一个非常基本的问题，但无论如何都在这里.

I think this is a pretty basic question, but here it is anyway.

我需要编写一个Python脚本来检查以确保某个进程(例如notepad.exe)正在运行.如果该进程正在运行，则什么也不做.如果不是，请启动它.该怎么做.

I need to write a python script that checks to make sure a process, say notepad.exe, is running. If the process is running, do nothing. If it is not, start it. How would this be done.

我在Windows XP上使用Python 2.6

推荐答案

有两个选项，

1:更粗略但显而易见的是针对以下内容进行文本处理:

1: the more crude but obvious would be to do some text processing against:

os.popen('tasklist').read()

2:一个更复杂的选择是使用pywin32并研究win32 API以确定正在运行的进程.

2: A more involved option would be to use pywin32 and research the win32 APIs to figure out what processes are running.

3:WMI(我刚刚找到了)，并且<一个href ="http://www.computerperformance.co.uk/vbscript/wmi_process.htm" rel ="nofollow noreferrer">这是一个vbscript 示例，说明如何通过WMI在机器上查询进程.

3: WMI (I found this just now), and here is a vbscript example of how to query the machine for processes through WMI.
