Python スクリプト操作を使用して、Linux でファイル権限の管理と制御を実装します。

import os def get_file_permission(file_path): # 获取文件的权限信息 permission = oct(os.stat(file_path).st_mode)[-3:] return permission # 示例 file_path = "/home/user/test.txt" file_permission = get_file_permission(file_path) print("文件权限：", file_permission)

import os def change_file_permission(file_path, permission): # 修改文件的权限 try: os.chmod(file_path, int(permission, 8)) print("文件权限修改成功！") except Exception as e: print("文件权限修改失败：", e) # 示例 file_path = "/home/user/test.txt" permission = "644" change_file_permission(file_path, permission)

import os import pwd import grp def get_file_owner_group(file_path): # 获取文件的所有者和所属组 uid = os.stat(file_path).st_uid gid = os.stat(file_path).st_gid owner = pwd.getpwuid(uid).pw_name group = grp.getgrgid(gid).gr_name return (owner, group) # 示例 file_path = "/home/user/test.txt" file_owner, file_group = get_file_owner_group(file_path) print("文件所有者：", file_owner) print("文件所属组：", file_group)

import os import pwd import grp def change_file_owner_group(file_path, new_owner, new_group): # 修改文件的所有者和所属组 try: uid = pwd.getpwnam(new_owner).pw_uid gid = grp.getgrnam(new_group).gr_gid os.chown(file_path, uid, gid) print("文件所有者和所属组修改成功！") except Exception as e: print("文件所有者和所属组修改失败：", e) # 示例 file_path = "/home/user/test.txt" new_owner = "new_user" new_group = "new_group" change_file_owner_group(file_path, new_owner, new_group)
