(Python)问题与Linux命令unrar,不能为我的生活找出为什么
问题描述:
所以最近我在这里做了一个线程需要帮助的脚本,应该自动为我提取.rar
文件和.zip
文件,没有用户交互。随着人们的各种帮助我做出这样的:(Python)问题与Linux命令unrar,不能为我的生活找出为什么
import os
import re
from subprocess import check_call
from os.path import join
rx = '(.*zip$)|(.*rar$)|(.*r00$)'
path = "/mnt/externa/Torrents/completed/test"
for root, dirs, files in os.walk(path):
if not any(f.endswith(".mkv") for f in files):
found_r = False
for file in files:
pth = join(root, file)
try:
if file.endswith(".zip"):
print("Unzipping ",file, "...")
check_call(["unzip", pth, "-d", root])
found_zip = True
elif not found_r and file.endswith((".rar",".r00")):
check_call(["unrar","e","-o-", pth, root])
found_r = True
break
except ValueError:
print ("OOps! That did not work")
我第一次运行.rar文件这个脚本它工作惊人,它提取文件到正确的目录和一切,但如果我再次运行它打印错误:
Extracting from /mnt/externa/Torrents/completed/test/A.Film/Subs/A.Film.subs.rar
No files to extract
Traceback (most recent call last):
File "unrarscript.py", line 20, in <module>
check_call(["unrar","e","-o-", pth, root])
File "/usr/lib/python2.7/subprocess.py", line 541, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['unrar', 'e', '-o-', '/mnt/externa/Torrents/completed/test/A.Film/Subs/A.Film.subs.rar', '/mnt/externa/Torrents/completed/test/A.Film/Subs']' returned non-zero exit status 10
所以我试图用一个try /除外,但我不认为我这样做是正确的,任何人都可以对这个剧本收尾帮助吗?
答
当unrar返回一个不同于0的错误代码时,check_call
引发了CalledProcessError
异常。
你的错误信息显示此:
returned non-zero exit status 10
Rar.txt
含有错误代码如下表:(可在WinRAR的安装文件夹中找到)
Code Description
0 Successful operation.
1 Non fatal error(s) occurred.
2 A fatal error occurred.
3 Invalid checksum. Data is damaged.
4 Attempt to modify an archive locked by 'k' command.
5 Write error.
6 File open error.
7 Wrong command line option.
8 Not enough memory.
9 File create error
10 No files matching the specified mask and options were found.
11 Wrong password.
255 User stopped the process.
我看你用-o-
为“跳过现有文件“。当试图覆盖文件。如果打包文件已经存在,则返回错误代码10。如果您立即重新运行您的脚本,则正常引发此错误。
C:\>unrar e -o- testfile.rar
UNRAR 5.30 freeware Copyright (c) 1993-2015 Alexander Roshal
Extracting from testfile.rar
No files to extract
C:\>echo %errorlevel%
10
你或许可以做这样的事情来处理它:
except CalledProcessError as cpe:
if cpe.returncode == 10:
print("File not overwritten")
else:
print("Some other error")
我看你尝试提取vobsubs。 vobubs rar中的.sub rar文件名也相同。
是那里的文件? “没有文件提取”似乎unrar无法找到它 – marcadian
是的,该文件在那里。 – nillenilsson
