非交互地将参数传递给交互式程序 [英] Passing arguments to an interactive program non-interactively

问题描述

我有一个bash脚本，该脚本使用read命令以交互方式读取命令的参数，例如yes/no选项.有没有办法在将默认选项值作为参数传递的非交互式脚本中调用此脚本?

I have a bash script that employs the read command to read arguments to commands interactively, for example yes/no options. Is there a way to call this script in a non-interactive script passing default option values as arguments?

这不仅是我必须传递给交互式脚本的一种选择.

It's not just one option that I have to pass to the interactive script.

推荐答案

对于更复杂的任务，有expect(

For more complex tasks there is expect ( http://en.wikipedia.org/wiki/Expect ). It basically simulates a user, you can code a script how to react to specific program outputs and related stuff.

这在ssh禁止向其传递密码的情况下也适用.

This also works in cases like ssh that prohibits piping passwords to it.
