将系统命令转换为 python 以进行文件搜索和删除 [英] Converting a system command to python for file search and delete

问题描述

我有一个 cron 作业，它使用以下命令根据文件的年龄删除文件:

I have a cron job that deletes files based on their age using the command:

find /path/to/file/ -type f -mmin +120|xargs -I file rm 'file'

但是我想将该命令集成到一个 python 脚本中，该脚本涉及该任务以及其他也在 cron 上运行的东西.

However I'd like to integrate the command into a python script which involves the task as well as other things that also run on cron.

我知道我可以将命令按原样插入 Python 脚本中，它可能会运行 find，但是我很想知道有一种更以 Python 为中心的方式来完成此任务，以及这可能带来哪些其他好处?

I understand I could just plonk the command as it is into the Python script and it would probably run find, however I'm interested to know there a more Python-centric way to accomplish this and what other benefits might that bring?

推荐答案

我的方法是:

import os
import time

def checkfile(filename):
    filestats = os.stat(filename) # Gets infromation on file.
    if time.time() - filestats.st_mtime > 120: # Compares if file modification date is more than 120 less than the current time.
        os.remove(filename) # Removes file if it needs to be removed.

path = '/path/to/folder'

dirList = os.listdir(path) # Lists specified directory.
for filename in dirList:
    checkfile(os.path.join(path, filename)) # Runs checkfile function.

我测试了它，它没有工作，所以我修复了代码，我可以确认它工作.

I tested it, it didn't work, so i fixed the code and i can confirm it works.
