git-merged-branches

git-merged-branches prints out the merge status of all local branches in a git repository.

Motivation

Sometimes you work on a repository for a few years and end up with hundreds of branches in a local git repository. Which ones have been merged already? Which ones are hiding useful code that you forgot you hadn't finished yet?

One solution is to use git branch --merged origin/master. However, that doesn't work if branches have been rebased or squashed as part of being merged. git-merged-branches instead uses git cherry to find equivalent commits on the base branch to see if the branch in question has been merged.

Usage

The script at ./git-merged-branches can be executed directly or via git if the script is on your PATH.

./git-merged-branches
git merged-branches

NOTE: This command moves HEAD, commits squashed branches, and generally does disrespectful things to the reflog. This should not cause any permanent damage, though.

Example

$ git merged-branches
Merged: feature-a
Merged: feature-b
Unmerged: feature-d
Merged: feature-y

The merged branches can be deleted by piping the output like so:

git merged-branches | grep Merged: | sed 's#^Merged: ##' | xargs git branch --delete --force
