Git: Merge a Remote branch locally

You can reference those remote-tracking branches ~(listed with git branch -r) with the name of their remote.

You need to fetch the remote branch:

  git fetch origin aRemoteBranch

If you wish to merge one of those remote branches on your native branch:

git checkout master

git merge origin/aRemoteBranch

Note 1: For a large repo with a long history, you will want to add the --depth=1 option when you use git fetch.

Note 2: These commands also work with other remote repository so you can set up an origin and an upstream if you are working on a fork.

Opposite scenario: If you want to merge one of your local branch on a remote branch (as opposed to a remote branch to a local one, as shown above), you

need to create a new native branch on top of said remote branch first:

git checkout -b myBranch origin/abranch

git merge anotherLocalBranch

The idea here is to merge "one of your local branch" (here anotherLocalBranch) to a remote branch (origin/aBranch).

For that, you create 1st "myBranch" as representing that remote branch: that's the git checkout -b myBranch origin/aBranch part.

And then you can merge anotherLocalBranch to it (to myBranch).
