Rapidly fulfil nearly all your Git requirements within just 8 minutes
In this tutorial, we will walk you through the essential steps for using Git, a popular version control system, to manage your code and collaborate with others effectively. We will focus on using Git for pushing your commits to a remote repository, checking your changes, and creating and merging branches.
Creating and Switching to a New Branch
Before you start working on new developments, it's recommended to create a separate branch. This allows you to work without disturbing the main branch (known as on GitLab and on GitHub). To create and switch to a new branch, use the following commands:
or
Making Code Changes and Committing
After creating your branch, make your desired changes to the local files. Once you're satisfied with your modifications, stage them using the command. Then, commit your changes with an informative message:
A good practice is to ensure each commit corresponds to a unique point of development.
Pushing the Branch to the Remote Repository
To push your branch to the remote repository, use the following command. The flag sets the upstream tracking, so future pushes can be done just with :
Opening a Pull Request or Merge Request
After successfully merging your work with the main branch, open the Merge/Pull Request page on your platform of choice (GitHub or GitLab) and look for the green "Merge" button. If you encounter a grey "Merge" button, it means there is a conflict with changes made by someone else. In such a case, you need to do a rebase.
Resolving Conflicts and Rebasing
If there are conflicts between your changes and those of another user, you will need to resolve them before merging. Open the file(s) with conflicts, remove the markers and the not selected version of the code, and then commit your changes. After resolving conflicts, add those resolved files and commit your changes as usual.
To rebase, you need to be in your branch and get the last version of the code that your coworker merged. Then, use the following command to perform a rebase:
If you face a rare case where someone updated your branch while you were doing the rebase, you will have to restart all the steps of the rebase but pull from your branch, the remote branch.
Force Pushing with Lease
In some cases, you may need to force push your changes, especially when using . To force push with lease, use the following command:
Synchronizing with a Remote Git Project
To synchronize a local computer with a remote Git project, copy-paste the HTTPS link from the "Clone or Download" option on GitHub or GitLab and use the command.
Maintaining a Clean Project History
Using descriptive commit messages and creating focused feature branches help maintain a clean project history and facilitate code reviews. If using CI/CD pipelines, pushing triggers automated builds and tests to ensure code quality before merging.
Following these steps will help you navigate Git effectively and avoid common pitfalls. Happy coding!
