![]() ![]() ![]() Two Ways to Sync A Repo - Command Line and on GitHub You can also see that this fork is BEHIND the parent repo by 1 commits. Notice that you can tell by the upper left hand corner of the repo that this fork is owned by lwasser. Your repo being in sync refers to your fork having all of the commits or changes to the code and files that have been made to the parent repo. It is important to ensure that your fork is in sync with your colleague’s repo, ideally before making a new pull request to that repo. Your colleague and others in your group may be updating code while you are working. Your colleague’s repo is the final home for the code and content that you are working together on collaboratively. Pretend that you are working on a fork of your colleague’s repo. An Example Workflow Where Syncing Is Important If you sync your files regularly, you will ultimately reduce the risk of a merge conflict. When git does not know how to resolve a conflict, it will ask you to manually fix the conflict. which changes to keep and which to remove). Git does not know how to resolve the conflict (i.e. Syncing Your GitHub Repo Reduces the Chances of a Merge ConflictĪ merge conflict occurs when two people edit the same line in a file. Keeping your fork in sync with the central repo will reduce the risk of merge conflicts (a topic that you will learn more about in a later chapter). It is important keep your fork up to date or in sync with those changes as you work. When you are collaborating with others on a project, there are often changes being made to the repo that you (and others) are contributing to. Update your local clone of your forked repository (repo) using git pull.Sync your fork of a GitHub repo using.For more information, see " Addressing merge conflicts. If your local branch had unique commits, you may need to resolve conflicts. $ git merge upstream/main > Updating 34e91da.16c56ad > Fast-forward > README.md | 5 +++- > 1 file changed, 3 insertions(+), 2 deletions(-) For more information, see Basic Branching and Merging in the Git documentation. If your local branch didn't have any unique commits, Git will perform a fast-forward. $ git merge upstream/main > 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 This brings your fork's default branch into sync with the upstream repository, without losing your local changes. Merge the changes from the upstream default branch - in this case, upstream/main - into your local default branch. $ git checkout main > Switched to branch 'main' > From > * main -> upstream/mainĬheck out your fork's local default branch - in this case, we use main. > remote: Compressing objects: 100% (53/53), done. $ git fetch upstream > remote: Counting objects: 75, done. Commits to BRANCHNAME will be stored in the local branch upstream/BRANCHNAME. For more information, see " Configuring a remote repository for a fork."Ĭhange the current working directory to your local project.įetch the branches and their respective commits from the upstream repository. Syncing a fork branch from the command lineīefore you can sync your fork with an upstream repository, you must configure a remote that points to the upstream repository in Git. You can set the -force flag to overwrite the destination branch. If the changes from the upstream repository cause conflict then the GitHub CLI can't sync. gh repo sync owner/cli-fork -b BRANCH_NAME ![]() To update the remote fork from its parent, use the gh repo sync -b BRANCHNAME subcommand and supply your fork and branch name as arguments. To learn more about GitHub CLI, see " About GitHub CLI." When you're working from the command line, you can use the GitHub CLI to save time and avoid switching context. GitHub CLI is an open source tool for using GitHub from your computer's command line. Syncing a fork branch with the GitHub CLI If the changes from the upstream repository cause conflicts, GitHub will prompt you to create a pull request to resolve the conflicts. Review the details about the commits from the upstream repository, then click Update branch. On GitHub, navigate to the main page of the forked repository that you want to sync with the upstream repository.Ībove the list of files, select the Sync fork dropdown menu. ![]()
