用于查找 777 个文件和文件夹的脚本如何改进并使其与 python 2.4 (RHEL5) 兼容
script to find 777 files and folders how to improve and make it compatible in python 2.4 (RHEL5)
我有以下代码,我的第一个 python 脚本。它应该找到具有 777 权限的文件和文件夹,同时排除一些文件夹,如 /proc 等
有什么方法可以改进脚本吗?
#!/usr/bin/env python
import os, sys, socket,csv
from os.path import join
mode = int('777', 8)
results = {}
host = socket.gethostname()
results[host] = {}
exclude = ['proc', 'run']
def get_username(uid):
import pwd
try:
return pwd.getpwuid(uid).pw_name
except KeyError:
return uid
def find_files():
for (dirpath, dirnames, filenames) in os.walk('/'):
dirnames[:] = [d for d in dirnames if d not in exclude]
listoffiles = [join(dirpath, file) for file in filenames]
listoffiles += [join(dirpath,dir) for dir in dirnames]
for path in listoffiles:
try:
statinfo = os.stat(path)
except OSError:
#print(path)
pass
if (statinfo.st_mode & 0o777) == mode:
results[host][path] = {}
results[host][path]['owner'] = get_username(statinfo.st_uid)
results[host][path]['perm'] = oct(statinfo.st_mode & 0o777)
return results
find_files()
resultstxt = csv.writer(open('results_%s.csv' % host, 'w')) for hostname,data in results.items():
for path, attributes in data.items():
resultstxt.writerow([hostname, path, attributes['perm'], str(attributes['owner'])])
我还需要修改它,因为我们有几个遗留的 rhel5 服务器,并且代码无法正常工作,出现一个奇怪的语法错误:
File "./find777.py", line 34
if (statinfo.st_mode & 0o777) == mode:
^
使用 0777
而不是 0o777
。
八进制数字的 0o
前缀在 Python 2.4 中不可用。传统的 0
前缀一直有效到 Python 3.
