Identify merged branches

Rationale

• You might want to delete a branch (e.g. a feature branch).

• Before you do that, you might want to check whether that branch is fully merged.

• In others, you should know which branches are fully included in the current branch.

Command

• git branch --merged show the branches merged with the current branch.

• git branch --no-merged similar, but show the NOT merged

• Both can be used with the -r to include the remote tracking branch.

Notes

• From officials, merged branches means

  Branches whose tips are reachable from the specified commit (HEAD if not specified).

• If you traverse backwards from the commit specified (default: HEAD), do you see the tip (end) of those commits?

  • If so, then it's merged.

• You can provide the commit to travers from.

  • git branch --merged <name>

  • git branch --merged origin/<name>
