我如何编写一个“是"的脚本?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，我有几个脚本来填充数据并安装我使用的所有程序，但有几个程序会询问:

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"，我现在才知道该怎么做.

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

'yes' 命令 将无限期地回显y"(或您要求的任何内容).将其用作:

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

yes | command-that-asks-for-input

或者，如果需要大写的Y":

or, if a capital 'Y' is required:

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

---

如果你想传递'N'，你仍然可以使用yes:

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