Sync a fork of a repository to keep it up-to-date with the upstream repository.
Tip: Before you can sync your fork with an upstream repository, you must configure a remote that points to the upstream repository in Git.
Open Terminal (for Mac users) or the command prompt (for Windows and Linux users).
Change the current working directory to your local project.
Fetch the branches and their respective commits from the upstream repository. Commits to
masterwill be stored in a local branch,
git fetch upstream # remote: Counting objects: 75, done. # remote: Compressing objects: 100% (53/53), done. # remote: Total 62 (delta 27), reused 44 (delta 9) # Unpacking objects: 100% (62/62), done. # From https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY # * [new branch] master -> upstream/master
Check out your fork's local
git checkout master # Switched to branch 'master'
Merge the changes from
upstream/masterinto your local
masterbranch. This brings your fork's
masterbranch into sync with the upstream repository, without losing your local changes.
git merge upstream/master # Updating a422352..5fdff0f # Fast-forward # README | 9 ------- # README.md | 7 ++++++ # 2 files changed, 7 insertions(+), 9 deletions(-) # delete mode 100644 README # create mode 100644 README.md
If your local branch didn't have any unique commits, Git will instead perform a "fast-forward":
git merge upstream/master # Updating 34e91da..16c56ad # Fast-forward # README.md | 5 +++-- # 1 file changed, 3 insertions(+), 2 deletions(-)
Tip: Syncing your fork only updates your local copy of the repository. To update your fork on GitHub, you must push your changes.
