我有一个脚本可以向我报告一个目录中的所有文件,以便用户需要删除它们(这是一个管理不善的集群,没有真正的超级用户)。当我运行脚本时,我得到: OSError: [Errno 13] Permission denied: ' ls: : Permission denied 我不能写目录名(公司政策) 代码是:

#!/depot/Python-3.1.1/bin/python3.1
from stat import *
import stat
import sys
from collections import defaultdict
from pwd import getpwuid
import sys
sys.path.append('/remote/us01home15/ldagan/python')
import mailer
import os
import re
import glob
import subprocess
import pwd
def find_owner(file):
    return pwd.getpwuid(os.stat(file)[stat.ST_UID]).pw_name
if (len(sys.argv) < 1):
    sys.error('''Please input <runda number> <case number>''')
files_by_users=defaultdict(list)
runda_num="".join(sys.argv[1])
dir_basic='/berry/secure' 
case_num="".join(sys.argv[2])
secure_dir="".join([dir_basic,"/"])
i=1
dirs=[]
runda_case_dir="".join([dir_basic,'/',runda_num,'/',case_num ])
while (os.path.exists(secure_dir)):
    if (os.path.exists(runda_case_dir)):
        dirs.append(runda_case_dir)
    i+=1
    secure_dir="".join([dir_basic,str(i)])
    runda_dir="/".join([secure_dir,runda_num,case_num])

#now finding list of 
manager_email='ldagan@synopsys.com zafrany@synopsys.com'
def bull (msg):
    i=1


for dir in dirs:
    for root,dirs,files in os.walk(dir,onerror=bull):
        for file in files:
            file_full_name=os.path.join(root,file)
            files_by_users[find_owner(file_full_name)].append(file_full_name)
for username in files_by_users:
        sendOffendingNotice(username, file_by+users[username], manager_email)

def sendOffendingNotice(username,filenames,managerEmail):
    """gets file name & manager Email
        sends an Email to the manager for review. As there are no smtp
        definitions, mailx shall be used"""
    user_email=username+'@synopsys.com'
    message="""The following files \n"""  + """\n""".join(filenames) +"""\n""" + \
    """ which belongs to user """ + username +""" does not meet the required names's SPEC\nPlease keep it under a directory which has a proper case/star name\n"""
    message= """echo \"""" + message+ """" | mailx -s "Offending files" """ + managerEmail +" " #+user_email
    process=subprocess.Popen(message,shell=True)

该脚本不发送电子邮件,但会死掉。感谢您帮助新手。

听起来您的脚本以普通用户身份运行,并且没有读取目录的权限。

查看完整的错误消息会有所帮助(即使路径名已更改),因为它会告诉我们错误发生在哪一行。

但基本上解决方案是在try...except 块中捕获异常:

try:
    # Put the line that causes the exception here
    # Do not trap more lines than you need to.
    ...
except OSError as err:
    # handle error (see below)
    print(err)

特别是根据 S.Lott 的评论,请注意导致 OSErrors 的文件或目录可能正是您需要向其所有者发送电子邮件的文件。但是为了在他们的目录中读取,您的脚本可能需要以超级用户(或增强的)权限运行。
