git delete-squashed-branches

git delete-squashed-branches deletes local branches that have been squash-merged into the current branch. Part of git-extras, it detects branches whose commits were combined and merged as a single squash commit, which Git's standard --merged flag cannot identify.Squash merging creates a new commit combining all branch changes, leaving the original branch commits technically unmerged. This causes branch accumulation since git branch --merged won't flag them for deletion. The command uses tree comparison heuristics to detect when a branch's changes exist in the target branch despite differing commit history.Particularly useful for workflows on GitHub and GitLab where squash merging is the default merge strategy.
