Git Trim - Quickly remove merged, pruned, untracked, or stale branches

Have you ever needed to clean up stale or old local branches that have already been merged and deleted on GitHub? Jason McCreary has released a CLI tool for organizing local and remote branches:

Cleaning up thousands of dangling references in Git repos everywhere - another "Garbage Man" production. 🗑😎https://t.co/fW4yTkPSJt

The git-trim command is a way to quickly remove merged, pruned, untracked, and stale branches in Git repositories:

# Removes local branches where its remote branch no longer exists
git trim
git trim --pruned
 
# Removes local branches already merged into the current branch
git trim --merged
 
# Removes local branches without commits in the last 3 months
git trim --stale
 
# Removes local branches not tracking a remote branch
git trim --untracked
 
# Removes all local branches except the current branch (requires confirmation)
git trim --all

You can also combine these when it makes sense, such as removing merged and stale branches:

git-trim --merged --stale

You can download and try this command out via NPM or as an Oh-My-Zsh plugin. If you'd like to learn more about the source code, you can check it out on GitHub at jasonmccreary/git-trim.
