如何使用批处理文件自动输入shell脚本的答案？

I have a shell script that that has some questions that nee to be answered(Answers are in form of strings). I have to make another batch file that opens the shelll script and answers the questions automatically. the problem i am facing is that when i open the shell script on cmd using my batch file, i get stuck on the shell script. Any ideas on what commands i will need to input the answers automatically?

Generically, you need to use either redirection with a temporary file, or a pipe.

通常,您需要使用临时文件或管道重定向。

I'll assume your controller batch file needs to provide three answers to script.bat.

我假设您的控制器批处理文件需要为script.bat提供三个答案。

Using Redirection

@echo off
>answers.txt echo answer1
>>answers.txt echo answer2
>>answers.txt echo answer3
call script.bat <answers.txt
del answers.txt

or you can use a single redirection if you use parentheses

或者,如果使用括号,则可以使用单个重定向

@echo off
>answers.txt (
  echo answer1
  echo answer2
  echo answer3
)
call script.bat <answers.txt
del answers.txt

Using a Pipe

@echo off
(
  echo answer1
  echo answer2
  echo answer3
) | script.bat
