Bypassing prompt (to press return) in homebrew install script
提问by cakes88
Very simple script that installs homebrew:
安装自制软件的非常简单的脚本：
#!/bin/bash
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
The output gives:
输出给出：
==> 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
How do I press enter in a script like this? Would expect be the best route?
如何在这样的脚本中按 Enter 键？期望是最好的路线吗？

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:
阅读https://raw.github.com/Homebrew/homebrew/go/install的源代码——它只提示 stdin 是否为 TTY。如果您从 重定向 stdin /dev/null，它根本不会提示。所以：
ruby \
-e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" \
</dev/null

Per the lead maintainer of Homebrew:
echo | /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

This works fine for me,
这对我来说很好用，
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null
