Git: How to find all branches that were never merged back into master

Question

We have a fairly large GIT repo and I would like to remove branches that were never merged back into master.

The reverse is fine too - a way to list all branches tha

Answer 1

git help branch says:

   With --contains, shows only the branches that contain the named commit
   (in other words, the branches whose tip commits are descendants of the
   named commit). With --merged, only branches merged into the named
   commit (i.e. the branches whose tip commits are reachable from the
   named commit) will be listed. With --no-merged only branches not merged
   into the named commit will be listed. If the <commit> argument is
   missing it defaults to HEAD (i.e. the tip of the current branch).

Hence, for finding all branches already merged to master you can use git branch --merged master.

Answer 2

git branch --no-merged master

Or for the other way, git branch --merged master
