How to delete local merged branches in git in seconds

The fact that we can delete local merged branches in git within seconds is a discovery to me.

Let's take a look at the code:

1git branch --merged | egrep -v  "(^\*|main|master|development|production|release-*|gh-pages)" | xargs git branch -d

1. git branch --merged: lists all the merged branches
2. egrep -v "(^\*|main|master|development|production|release-*|gh-pages)": excludes the matching branches (including the current one)
3. xargs git branch -d: deletes the branches

Just make to sure to put all the branch names in the second step which are not supposed to be deleted. Any branch which does not match the criteria will get deleted.

And finally, you can create an alias for this command in your .zshrc so you don't have to type it every time:

1alias dumb="git branch --merged | egrep -v  "(^\*|main|master|development|production|release-*|gh-pages)" | xargs git branch -d"
