A nice git function to clean up your local branches. Drop in your bashrc file(s).

git-prune-local.sh

# Deletes local branches that have been deleted on the remote
function gpl() {
  # Determine the name of the trunk
  trunkname=$(git symbolic-ref --short refs/remotes/origin/HEAD | sed 's@^origin/@@')

  # List branches that have been removed from origin and write to file
  git branch --merged $(git rev-parse $trunkname) | awk '{$1=$1};1' | egrep -v "(^\*|^\s*($trunkname)$)" > /tmp/branchesToPurge

  # Open the file for editing
  vim /tmp/branchesToPurge

  # Print list of branches to be deleted
  echo "The following branches will be deleted:"
  cat /tmp/branchesToPurge

  # Ask if we should proceed
  read -p "Are you sure you want to delete these branches (y/n)? " answer
  case ${answer:0:1} in
  y | Y)
    echo "Deleting..."
    # Delete branches listed in file
    xargs git branch -D </tmp/branchesToPurge
    ;;
  *)
    echo "Aborted"
    ;;
  esac
}
