Python os.system()将文本输入脚本 [英] Python os.system() input text to script

问题描述

我有一个需要自动化的脚本，所以它是一个.sh脚本，我想在python脚本中运行:像这样:

I have a script that I need to automate, so it's a .sh script which I want to run inside a python script: something like this:

import os
os.system('./script.sh -p 1234')

脚本script.sh需要用户输入3个字段，1)sudo密码，2)字符串和3)字符串.

The script script.sh needs the user to input 3 fields, 1) the sudo password, 2) a string and 3) a string.

Enter password for user: xxxx  #typed by me
Enter Auth Username: xxxx      #typed by me
Enter Auth Password: xxx       #typed by me

如何使python脚本将这3个所需的值键入/插入/传递给script.sh.

How can I make the python script to type/insert/pass those 3 needed values to script.sh.

推荐答案

您可以使用subprocess.Popen启动脚本，并使用communicate方法传递输入.像这样:

You can use subprocess.Popen to start the script and the communicate method to pass it input. Something like this:

import subprocess

p = subprocess.Popen(['./script.sh', '-p', '1234'], 
                     stdin=subprocess.PIPE, stdout=subprocess.PIPE)
stdout, stderr = p.communicate(input='password\nauth username\nauth password\n')
