This git alias will open a web browser and take you to a project's github page when you
type git hub in a checked-out project directory.
For OS X:
git config --global alias.hub '!open $(echo $(git config --get remote.origin.url) | perl -pe "s|git\@github\.com:|https://github.com/|")'
For Linux:
git config --global alias.hub '!xdg-open $(echo $(git config --get remote.origin.url) |perl -pe "s|git\@github\.com:|https://github.com/|")'
