在自制绕过提示（preSS回报）安装脚本 [英] Bypassing prompt (to press return) in homebrew install script

问题描述

很简单的脚本，安装自制软件：

Very simple script that installs homebrew:

  #!/bin/bash

  ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

输出给出了：

==> This script will install:
/usr/local/bin/brew
/usr/local/Library/...
/usr/local/share/man/man1/brew.1

Press RETURN to continue or any other key to abort

我如何preSS在这样的输入脚本？所期望的是最佳路线？

How do I press enter in a script like this? Would expect be the best route?

推荐答案

阅读的<一个源href=\"https://raw.github.com/Homebrew/homebrew/go/install\">https://raw.github.com/Homebrew/homebrew/go/install - 如果标准输入是一个TTY它只是提示。如果您重定向从的/ dev / null的标准输入，它不会提示的。所以：

Reading the source of https://raw.github.com/Homebrew/homebrew/go/install -- it only prompts if stdin is a TTY. If you redirect stdin from /dev/null, it won't prompt at all. So:

ruby \
  -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" \
  </dev/null
