如何编写“是"脚本?安装程序的响应? [英] How do I script a "yes" response for installing programs?

问题描述

我使用Amazon Linux实例，并且有几个脚本来填充数据并安装与我一起使用的所有程序，但是有几个程序会问:

I work with Amazon Linux instances and I have a couple scripts to populate data and install all the programs I work with, but a couple of the programs ask:

Do you want to continue [Y/n]?

并暂停安装.我想在所有情况下都自动回答"Y"，我现在确定该怎么做.

and pause the install. I want to auto answer "Y" in all cases, I'm just now sure how to do it.

推荐答案

是"命令将无限期地回显"y"(或您要求的任何结果).用作:

The 'yes' command will echo 'y' (or whatever you ask it to) indefinitely. Use it as:

yes | command-that-asks-for-input

或者，如果需要大写字母"Y":

or, if a capital 'Y' is required:

yes Y | command-that-asks-for-input
