OS X: Opens the specified file/directory in GitHub via your browser

hubb.sh

# Usage from within a Git repo:
# 
#   hubb public/javascripts/app.js
#     # Opens `https://github.com/<repo>/blob/<branch>/public/javascripts/app.js`
#     # in your browser.
#
#   hubb
#     # Opens `https://github.com/<repo>` in your browser.
hubb(){
  repo=$(git config remote.origin.url | sed "s/^git@github\.com:\(.*\)\.git$/\1/")
  branch=$(cat .git/HEAD | sed "s/.*\/\(.*\)$/\1/")
  if [ $1 ]; then
    kind=$([[ $1 =~ \/$ ]] && echo "tree" || echo "blob")
    open "https://github.com/$repo/$kind/$branch/$1"
  else
    # Like `hub browse`: https://github.com/defunkt/hub
    open "https://github.com/$repo/tree/$branch"
  fi
}

Definitely; I called it hubb as shorthand for hub browse, but with the feature I wanted.
