如何在Python中运行没有扩展名的bash文件

Question

我想知道如何在Python中使用此页中的脚本：

http://www.fmwconcepts.com/imagemagick/textcleaner/index.php

下载时没有分机。我试着把它改名为“文本清理器.sh“并运行以下命令：

import subprocess

subprocess.check_call(['textcleaner.sh', '-g', '-e', 'normalize', 'input_image.jpg', 'output_image.jpg'])

但是这样做的时候我得到了一个错误：

Traceback (most recent call last):
  File "C:/Users/ikdem/PycharmProjects/McAffeeeeeee/bash test.py", line 11, in <module>
    subprocess.check_call(['textcleaner.sh', '-g', '-e', 'normalize', 'opl-small-1.jpg', 'output.jpg'])
  File "C:\Users\ikdem\AppData\Local\Programs\Python\Python35\lib\subprocess.py", line 579, in check_call
    retcode = call(*popenargs, **kwargs)

Windows不支持在其二进制加载程序中解析Unix样式的shebang，因此需要调用sh.exe或bash.exe的副本，将路径传递给脚本，后跟脚本的参数。您通常可以在MinGW或MSYS安装中找到这些可执行文件。你知道吗
