Keep clean your git repos!


Many developers don't keep their local repositories clean. There is a way how to automate it though. Let's look at a few useful commands:

To clean refs to nonexistent branches in the remote:


$ git fetch --prune

--prune before fetching, remove any remote-tracking references that no longer exist on the remote.

To estimate how many branches merged into dev:


$ git branch --merged dev | wc -l

--merged option can filter list to branches that you have merged into the given branch. Squash and rebase merges usually aren't detected by --merged.

List of branches merged into dev:


$ git branch --merged dev

List of remote branches merged into dev:


$ git branch --merged dev --remote

If you are courageous then:


$ git branch --merged dev | egrep -v "(^\*|master|dev)" | xargs git branch -d

It removes all local branches that merged into dev (except dev and master).

This is a potentially damaging operation. It can delete branches actually needed.

So if you use the different approach to work with Git, you could remove some of branches manually instead. I hope you do not store all old branches, do you?
