Reload all installed homebrew formulas. (I found this useful after updating from OS X 10.8.x to 10.9.)

Mavericks Update Notes.md

• Download the Command Line Tools (OS X Mavericks) from https://developer.apple.com/downloads

• From the Terminal:

  sudo xcode-select --reset sudo xcode-select --switch /Library/Develop/CommandLineTools

• Install openssl with homebrew:

  brew remove openssl brew install openssl

• Reinstall rbenv and ruby-build

  brew remove --force ruby-build brew remove --force rbenv brew install rbenv ruby-build if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

• Install the latest ruby with rbenv and use the openssl installed above:

  CONFIGURE_OPTS="--with-openssl-dir=brew --prefix openssl --without-tcl --without-tk" rbenv install 2.0.0-p451 rbenv rehash

• Reload a bunch of brew packages

  function reload_brew() { local pkg=${1} brew unlink ${pkg} && brew remove ${pkg} && brew install ${pkg} }

  Do either of the following:

  # The somewhat manual method:
  

  for p in ffmpeg x264 libvorbis lame faac libffi libtiff libogg libyaml; do reload_brew ${p} done

  OR

  Reload all pkgs installed in brew:

  pkgs=brew list for p in ${pkgs}; do reload_brew ${p} done

reload_brew_formulas.sh

#!/bin/bash

# the unlink then remove probably isn't necessary but it's what I ran
function reload_brew() {
  local pkg=${1}
  brew unlink ${pkg} && brew remove ${pkg} && brew install ${pkg}
}

pkgs=`brew list`
for p in ${pkgs}; do
  reload_brew ${p}
done
