Masterブランチにマージ済みのローカルブランチを一括削除する方法

More than 3 years have passed since last update.

目的:
リリースが終わって、Masterブランチにマージ済みの手元のブランチを一括削除したい。

コマンド

git fetch && git branch --merged origin/master | grep -v "^\s*master" | grep -v "^*" | xargs git branch -D

概要

git branch --merged {COMMIT} で特定のCOMMITを指定してマージ済みのブランチを取得できる。そこからカレントブランチとmasterブランチを除外して削除。

ちなみにローカルにあるリモートブランチへの参照は

git remote prune origin

とか

git fetch -p

とかで消せる。

aliasを貼っておくと更に便利

alias git-delete-merged-br='git fetch && git branch --merged origin/master | grep -v "^\s*master" | grep -v "^*" | xargs git branch -D'
