How Do I Update or Sync a Forked Repository on Github?
To update or sync a forked repository on GitHub with its original upstream repository (the one you forked from), you need to perform a few steps. Here's how you can do it:
Step 1: Add the Upstream Remote
First, you need to add the original upstream repository as a remote to your forked repository. You typically only need to do this once:
git remote add upstream <upstream-repository-url>
Replace <upstream-repository-url> with the URL of the original upstream repository. You can usually find this URL on the original repository's GitHub page.
Step 2: Fetch Changes from Upstream
Fetch the changes from the upstream repository:
git fetch upstream
This command will fetch all branches and commits from the upstream repository.
Step 3: Merge or Rebase Changes
Now, you can merge or rebase the changes from the upstream repository into your local branch. You have two options:
Option 1: Merge Changes
git checkout master # or the branch you want to update
git merge upstream/master
This command will merge the changes from the upstream repository's master branch into your local branch.
Option 2: Rebase Changes (Recommended for Clean History)
git checkout master # or the branch you want to update
git rebase upstream/master
This command will rebase your local changes on top of the changes from the upstream repository's master branch, resulting in a cleaner commit history.
Step 4: Push Changes to Your Fork
Finally, push the merged or rebased changes to your forked repository on GitHub:
git push origin master # or the branch you updated
This command will push the changes to your forked repository on GitHub, updating it with the changes from the upstream repository.
Note:
- You may need to resolve any merge conflicts that occur during the merge or rebase process.
- Make sure you have permission to push changes to your forked repository on GitHub.
- It's a good practice to keep your forked repository updated with the changes from the upstream repository to stay in sync with the latest developments.
