Python:子进程并运行具有多个参数的 bash 脚本

2022-01-18 00:00:00 python subprocess popen bash arguments

问题描述

如何使用 subprocess 模块运行 bash 脚本，我必须为其提供几个参数?

How do I go about running a bash script using the subprocess module, to which I must give several arguments?

这是我目前正在使用的:

This is what I'm currently using:

subprocess.Popen(['/my/file/path/programname.sh', 'arg1 arg2 %s' % arg3], 
    shell = True)

bash 脚本似乎没有接受任何参数.非常感谢任何见解！

The bash script seems not to be taking any of the parameters in. Any insights are greatly appreciated!

解决方案

将参数作为列表传递，参见 文档中的第一个代码示例:

Pass arguments as a list, see the very first code example in the docs:

import subprocess

subprocess.check_call(['/my/file/path/programname.sh', 'arg1', 'arg2', arg3])

如果 arg3 不是字符串；在传递给 check_call() 之前将其转换为字符串:arg3 = str(arg3).

If arg3 is not a string; convert it to string before passing to check_call(): arg3 = str(arg3).
