Auto Update Brew: OS X Launchd job and script to automatically update homebrew

ReadMe.md

1. Place homebrewupdate.sh where ever you like, I use ~/bin/homebrewupdate.sh
2. Place the .plist file in ~/Library/LaunchAgents and update the path to your bash script
3. run launchctl load ~/Library/LaunchAgents/com.jb510.homebrewupdate.plist or whatever you've named your plist file.
4. check launchctl list | grep jb510 to see that it's running

Note: You might need to chmod +x homebrewupdate.sh

Note 2: you can run this manually to test your script ~/bin/homebrewupdate.sh

Future: Update this to also update casks https://github.com/buo/homebrew-cask-upgrade or using brew cask list | xargs brew cask reinstall
