Delete all branches except master and develop.

command.txt

git branch | grep -v "master\|develop" | xargs git branch -D

Delete everything but the current

git branch | grep -v `git branch --show-current` | xargs git branch -D

This command will delete the branch locally as well as remotely!
RUN WITH CAUTION

git branch -r | grep -Ev 'main|develop' | awk -F/ '/^  origin/ {print $2}' | xargs -I {} git push origin --delete {}

Result
It will print the following as the branch gets deleted.

To https://github.com/YourUserName/repository-name.git
 - [deleted]         email-config

I want to pass an argument. How can I do it?

What I want to do is something like this.

#on alias
delo=git branch | grep -v "$variable here" | xargs git branch -D

#then all of the branch except branch-one will be removed/deleted.
~/project-one(branch) $ delo branch-one 

@jtors , you can do it like this

function delo() { git branch | grep -v "$1" | xargs git branch -D ;}

# use it as
delo "branchName"

Hi @nimi0112 thank you!
