Bypassing prompt (to press return) in homebrew install script

Per the lead maintainer of Homebrew:

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

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

This is what yes is for:

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