在自制安装脚本中绕过提示(按回车)

Question

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)"

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

如何在这样的脚本中按Enter键？期望是最好的路线？

Answer 1

阅读https://raw.github.com/Homebrew/homebrew/go/install的来源- 它只会提示stdin是否为TTY.如果你重定向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

Answer 2

这yes是为了什么:

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

Answer 3

根据 Homebrew 的首席维护者：

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