If you use your Mac for any period of time you will find the need to open a document with a different program other than the one that is set as default. The "Open With" menu appears in the Finder whenever you right-click or control-click on the icon of a document. The "Open With" commanded is designed to give you a list of alternative choices to handle the file that you've selected, but after long-term use you will find this list can get a little bit messy.

Duplicate entries in your "Open With" menu can be easily cleaned via a simple terminal command. In this video I will also show you how to create a bash script to make it easier to repeat this cleaning whenever needed as well as create aa Alfred workflow to do the same(requires the Alfred powerpack.) http://www.alfredapp.com/powerpack/

Below you'll find the commands used in the video. If you are creating the .bash_profile alias method remember you will have to quit and relaunch terminal for this to work.

Fix Duplicate "Open With" Terminal: /System/Library/Frameworks/CoreServices.­framework/Versions/A/Frameworks/LaunchSe­rvices.framework/Versions/A/Support/lsre­gister -kill -r -domain local -domain user;killall Finder;echo "Open With has been rebuilt, Finder will relaunch"

Fix Duplicate "Open With" via Bash alias: alias fixow='/System/Library/Frameworks/Co­reServices.framework/Versions/A/Framewor­ks/LaunchServices.framework/Versions/A/S­upport/lsregister -kill -r -domain local -domain user;killall Finder;echo "Open With has been rebuilt, Finder will relaunch"'

If you are a little shy of monkeying around in terminal and bash you can use utilities like Onyx or Cocktail to get the job done.
