Chmod问题使用python更改文件权限 [英] Chmod issue to change file permission using python

问题描述

我希望更改所有文件的文件权限，以便使用python脚本为目录中的所有用户执行读写操作。但是，在运行脚本后，当我通过右键单击检查文件权限时，它只显示我的权限，并且仅显示每个人具有读取权限的组的权限。我在以下脚本中有什么问题：

I am looking to change the file permission to all files to read write and execute for all the users in a directory using a python script. However, after running the script when I check the file permission doing the right click, it only shows the permissions for me and for the group everyone it only has read permission. Is there anything wrong I am doing in the following script:

import os
import pdb

for dirpath, dirnames, filenames in os.walk('M:\intra\EU'):
    for filename in filenames:
        path = os.path.join(dirpath, filename)
        os.chmod(path, 0o777) # for example

I found a solution here :)

在Windows中使用Python设置文件夹权限

import win32security
import ntsecuritycon as con
import os
import pdb
userx, domain, type = win32security.LookupAccountName ("", "Everyone")
directory='M:\intra\EU'
for dirpath, dirnames, filenames in os.walk('M:\intra\EU'):
    for FILENAME in filenames:
        sd = win32security.GetFileSecurity(directory+'\\'+FILENAME, win32security.DACL_SECURITY_INFORMATION)
        dacl = sd.GetSecurityDescriptorDacl()   # instead of dacl = win32security.ACL()
        dacl.AddAccessAllowedAce(win32security.ACL_REVISION, con.FILE_ALL_ACCESS, userx)
        sd.SetSecurityDescriptorDacl(1, dacl, 0)
        win32security.SetFileSecurity(directory+'\\'+FILENAME, win32security.DACL_SECURITY_INFORMATION, sd)
