brew コマンド（複数）をまとめてスクリプト化

こんにちは。
homebrew で動かすことが多い brew コマンド（複数）はまとめてスクリプト化。

#!/usr/bin/ruby
require 'yaml'

brewcmds_yml = <<EOS
- "brew list --versions \| awk '{printf(\\"%-18s %s\\\\n\\",$1,$NF)}'"
- "brew cask list \| cut -d' ' -f1 \| xargs -I % bash -c \\"echo -n %' '; ls -C /opt/homebrew-cask/Caskroom/%\\" \| awk '{printf(\\"%-18s\\",$1);$1=\\"\\";print}'"
- "brew --config"
- "brew tap"
- "brew update"
- "brew doctor"
- "brew outdated"
EOS

for brewcmd in YAML.load(brewcmds_yml)
    puts "% " + brewcmd.gsub(/\|.*/, "")
    puts `#{brewcmd + " 2>&1"}` # for sh/bash
end

brewcmd = "brew outdated"
brew_outdated = `#{brewcmd + " 2>&1"}`.gsub(/\n/, " ") # for sh/bash
puts "% " + brewcmd
puts `brew info #{brew_outdated}` unless brew_outdated.empty?

exit(0)

• brew cask list ＋バージョン表示 も加えてあります。
