Git is a well-organized distributed version control system that can be very effective in managing source code in a distributed team of developers. When different developers are working on different product features, once they have completed the complete feature, they have to merge or synchronize the master branch with their updated work.

In Git, a repository is a category of projects that we bring in on the Internet, a private server, or a network somewhere.

Remote repositories serve as a way for developers to share parts of their work with team members. They can then fetch it in their local environment.

Whenever our local branches are introduced or created, once they are ready to be synchronized and the functional tasks are completed, we will need to synchronize our local repository with the remote repository again and again.

Synchronizing files is the process of making similar updates to two or more files. These are branches of the developer's local environment, and once they need to deploy the entire task to the server and hand it over to the client, they will synchronize it to the master branch.

Synchronize branches with Master in Git

Developers of large projects work in a team on different tasks simultaneously. While we are working on our branch, others may push some of their commits to the master branch.

So, to fix this situation, we should keep our repository in sync with the recent changes by pulling the latest work, which should be updated every day or two to thrice a day.

First, we will get the recent changes by checking out the master branch. Before doing that, we must commit all the changes to the remote branch and then pull it from upstream with the following Git command:

$ git checkout master
$ git pull upstream master

By doing this, our local master branch will be updated to the master branch, but the feature branch will remain the same. To update it, we will also rebase it using the Git command mentioned below:

$ git checkout my_feature_branch
$ git rebase master

Although this is a smooth process, if Git does not respond to the automatic merge, it will result in a merge conflict. We have to eliminate this conflict by opening the conflicting file present in a text editor or if you have visual studio code.

Multiple conflicts may occur in the same file, indicated by red markers. Resolve them manually by editing the file, then adding the file to the index, then rebasing, as follows:

$ git add path/to/file
$ git rebase --continue

Now that both the master and feature branches are updated and the changes in the feature branch are ready, we merge them into the master branch as follows.

$ git checkout master
$ git merge my_feature_branch

This will bring our feature branch in sync with the master branch, and all of our latest code will be merged into the master branch.
