Two scripts for doing branch matainence.

git-clean-branches

#!/bin/bash

remote=${1:-origin}

declare -a branches
declare -a local_branches
for branch in $(git branch --merged | egrep -v '(^[*])|(master)|(staging)|(production)|(^\s*$)'); do
  branch_remote=$(git config --get branch.$branch.remote)

  if [ "$branch_remote" == "$remote" ]; then
    branches+=($branch)
  fi

  if [ -z $branch_remote ]; then
    local_branches+=($branch)
  fi
done

if [ ${#branches[*]} -ne 0 ]; then
  echo Cleaning:
  echo ${branches[*]}

  logfile=/tmp/$(basename ${0}).log
  echo -n > $logfile
  for branch in ${branches[*]}; do
    #If we can delete the branch remotely, delete it locally
    git push origin :$branch 2>> $logfile
    git branch -d $branch 2>> $logfile
  done

  cat $logfile
fi

echo "Did not clean local branches:"
echo ${local_branches[*]}

remotes=$(git remote)
for remote in $remotes; do
  git remote prune $remote
done

echo "Running garbage collection"
git gc 2>/dev/null

git-localize-branches

#!/bin/bash

if [ $# -ne 1 ]; then
  echo "Usage: $(basename ${0}) <remote>"
  exit 2
fi

remote_name=$1

logfile=/tmp/$(basename ${0}).log
echo -n > $logfile
for b in $(git branch -r | grep -v "${remote_name}/HEAD" | grep "\s*${remote_name}/" | sed "s#\s*${remote_name}/##"); do
  git branch -t $b "${remote_name}/$b" 2>> $logfile
done

if grep -v "fatal: A branch named" < $logfile; then
  exit 1
else
  exit 0
fi

git-clean-branches removes all the merged branches in the current workspace that can be deleted on their remote - the idea being that those are probably done.

git-localize-branches creates branches locally to track all the branches on

So:

git-localize-branches origin
git-clean-branches

should remove all the branches that are done and merged, until someone else pushes them back to origin.
