Github adding a repository as a fork from an existing clone

gitgithubversion control

So I have a git repository that I cloned from an upstream source on github. I made a few changes to it (that are uncommitted in the master branch). What I want to do is push my changes onto my github page as a new branch and have github still see it as a fork.

Is that possible? I'm fairly new to git and github. Did my question even make sense?

The easiest way that I can think of (which I'm sure is the most aroundabout way), is to fork the repo on github. Clone it locally to a different directory. Add the upstream origin repo. Create a branch in that new forked repo. Copy my code changes by hand into the new local repo. And then push it back up to my github.

Is this a common use case that there's a simpler way of doing it without duplicating directories?

I guess I'm asking here as opposed to SO since I'm on linux using command line git and the people here give better answers imo =]

You can do it all from your existing repository (no need to clone the fork into a new (local) repository, create your branch, copy your commits/changes, etc.).

  1. Get your commits ready to be published.

    Refine any existing local commits (e.g. with git commit --amend and/or git rebase --interactive).

    Commit any of your uncommitted changes that you want to publish (I am not sure if you meant to imply that you have some commits on your local master and some uncommitted changes, or just some uncommitted changes; incidentally, uncommitted changes are not “on a branch”, they are strictly in your working tree).

    Rename your master branch to give it the name you want for your “new branch”. This is not strictly necessary (you can push from any branch to any other branch), but it will probably reduce confusion in the long run if your local branch and the branch in your GitHub fork have the same name.

    git branch -m master my-feature

  2. Fork the upstream GitHub repository
    (e.g.) github.com:UpstreamOwner/repostory_name.git as
    (e.g.) github.com:YourUser/repository_name.git.

    This is done on the GitHub website (or a “client” that uses the GitHub APIs), there are no local Git commands involved.

  3. In your local repository (the one that was originally cloned from the upstream GitHub repository and has your changes in its master), add your fork repository as a remote:

    git remote add -f github github.com:YourUser/repository_name.git

  4. Push your branch to your fork repository on GitHub.

    git push github my-feature

  5. Optionally, rename the remotes so that your fork is known as “origin” and the upstream as “upstream”.

    git remote rename origin upstream
git remote rename github origin

    One reason to rename the remotes would be because you want to be able to use git push without specifying a repository (it defaults to “origin”).
