在python中通过命令查找进程 [英] Find processes by command in python

问题描述

在我的 Python 脚本中，我想检查 otherscript.py 当前是否正在 (Linux) 系统上运行.psutil 库看起来是一个不错的解决方案:

In my Python script, i want to check if otherscript.py is currently being run on the (Linux) system. The psutil library looked like a good solution:

import psutil
proc_iter = psutil.process_iter(attrs=["name"])
other_script_running = any("otherscript.py" in p.info["name"] for p in proc_iter)

问题在于 p.info["name"] 只给出了一个进程的可执行文件的名称，而不是完整的命令.因此，如果在系统上执行 python otherscript.py，p.info["name"] 将只是该进程的 python，并且我的脚本无法检测 otherscript.py 是否是正在运行的脚本.

The problem is that p.info["name"] only gives the name of the executable of a process, not the full command. So if python otherscript.py is executed on the system, p.info["name"] will just be python for that process, and my script can't detect whether or not otherscript.py is the script being run.

是否有一种简单的方法可以使用 psutil 或其他一些库进行此检查?我意识到我可以将 ps 命令作为子进程运行并在输出中查找 otherscript.py，但如果存在，我更喜欢更优雅的解决方案.

Is there a simple way to make this check using psutil or some other library? I realize i could run the ps command as a subprocess and look for the otherscript.py in the output, but i'd prefer a more elegant solution if one exists.

推荐答案

不知道这样行不行

import psutil
proc_iter = psutil.process_iter(attrs=["pid", "name", "cmdline"])
other_script_running = any("otherscript.py" in p.info["cmdline"] for p in proc_iter)
