gitconfig aliases

gitconfig.sh

  # +cbranch+ returns the current branch you are on
  cbranch = !"git branch | grep '*' | cut -f2 -d' '"

  # +open-url+ opens the home page for this repository
  open-url = !"open `git remote show origin | grep 'Fetch URL' | ruby -e \"puts 'http://' + STDIN.read.scan(/Fetch URL: git@(.*)/).join.sub(':', '/').sub('.git','')\"`"

  # +open-branch+ opens the current branch in your default browser
  open-branch = !"open `git remote show origin | grep 'Fetch URL' | ruby -e \"puts 'http://' + STDIN.read.scan(/Fetch URL: git@(.*)/).join.sub(':', '/').sub('.git','') + \\\\\"/tree/#{%x|git cbranch|}\\\\\"\"`"

  # +open-sha+ opens the current SHA in your default browser
  open-sha = !"open `git remote show origin | grep 'Fetch URL' | ruby -e \"puts 'http://' + STDIN.read.scan(/Fetch URL: git@(.*)/).join.sub(':', '/').sub('.git','') + \\\\\"/commit/#{%x| git log -n1 --pretty=%H|}\\\\\"\"`"

  # e.g. - https://github.com/account/repos/pull/new/chore/branch-name-here
  open-pull = !"open `git remote show origin | grep 'Fetch URL' | ruby -e \"puts 'http://' + STDIN.read.scan(/Fetch URL: git@(.*)/).join.sub(':', '/').sub('.git','') + \\\"/pull/new/#{%x|git cbranch|}\\\"\"`"

  # +add-ignore+ downloads ignore files from Github and adds them to your local
  # .gitignore. TODO: This can be way awesomer.
  add-ignore = !"g(){ url="https://raw.github.com/github/gitignore/master/$1.gitignore" ; curl --output /dev/null --silent --head --fail "$url" ; if [ $? -eq 0 ]; then curl "$url" >> .gitignore && echo "Appended .gitignore with $url" ; else echo "$url doesnt exist." ; fi ; }; g"

I think you could avoid the piping & filtering in cbranch using this instead:

git symbolic-ref --short HEAD
