Homebrew went through an irritating phase where you had to use `brew search` instead of `brew cask search`, even though you still had to do `brew cask install`.

brew-alias.sh

brew () {
  if [[ "x$1" == "xcask" && "x$2" == "xsearch" ]]; then
    echo '`brew cask search` is broken, translating for you...'
    shift
    /usr/local/bin/brew $*
   else
    /usr/local/bin/brew $*
  fi
}

# for Vagrant it might be this, though I haven't tried it:

vagrant () {
  if [[ "x$1" == "xdown" ]]; then
    shift
    ${vagrant_binary} halt $*
  else
    #{vagrant_binary} $*
  fi
}
