[git] Track a new remote branch created on GitHub

I have already got a local master branch tracking the remote master branch of a github project. Now, a collaborator of mine has created a new branch in the same project, and I want to do the following accordingly:

1. create a new branch locally
2. make this new branch track the newly create remote branch.

How should I do it properly?

First of all you have to fetch the remote repository:

git fetch remoteName

Than you can create the new branch and set it up to track the remote branch you want:

git checkout -b newLocalBranch remoteName/remoteBranch

You can also use "git branch --track" instead of "git checkout -b" as max specified.

git branch --track newLocalBranch remoteName/remoteBranch

If you don't have an existing local branch, it is truly as simple as:

git fetch
git checkout <remote-branch-name>

For instance if you fetch and there is a new remote tracking branch called origin/feature/Main_Page, just do this:

git checkout feature/Main_Page

This creates a local branch with the same name as the remote branch, tracking that remote branch. If you have multiple remotes with the same branch name, you can use the less ambiguous:

git checkout -t <remote>/<remote-branch-name>

If you already made the local branch and don't want to delete it, see How do you make an existing Git branch track a remote branch?.

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.
