How to Handle Merge Conflicts in Git Like a Pro

Git is a powerful version control system that enables collaboration among developers. However, when multiple developers work on the same file or branch, it can result in merge conflicts. A merge conflict occurs when Git is unable to automatically merge changes from two different branches. In this situation, it requires manual intervention to resolve the conflict. In this article, we will discuss how to resolve merge conflicts in Git.

Step 1: Identify the Conflicted Files

When Git encounters a merge conflict, it will mark the conflicted files in your repository. To identify the conflicted files, run the following command in your terminal:

git status

This command will show you a list of all the conflicted files in your repository.

Step 2: Open the Conflicted File

Once you have identified the conflicted files, you need to open them in a text editor to resolve the conflict. You can use any text editor of your choice.

Step 3: Resolve the Conflicts

When you open the conflicted file, you will see the conflicting lines marked with Git conflict markers. The conflict markers look like this:

<<<<<<< HEAD 
This is the code from the current branch 
======= 
This is the code from the other branch 
>>>>>>> other-branch

The section between <<<<<<< HEAD and ======= is the code from the current branch, and the section between ======= and >>>>>>> other-branch is the code from the other branch. To resolve the conflict, you need to edit the code to remove the conflict markers and choose the correct version of the code.

Once you have resolved all the conflicts in the file, save the file and close the text editor.

Step 4: Add the Resolved File

After you have resolved the conflicts in the file, you need to add the resolved file to the staging area. To add the file to the staging area, run the following command:

git add <file>

Replace <file> with the name of the file that you have resolved.

Step 5: Commit the Changes

Once you have added the resolved file to the staging area, you need to commit the changes to your repository. To commit the changes, run the following command:

git commit -m "Resolved merge conflicts"

Replace Resolved merge conflicts with a commit message that describes the changes you have made.

Step 6: Push the Changes

After you have committed the changes, you need to push the changes to the remote repository. To push the changes, run the following command:

git push

This command will push the changes to the remote repository and complete the merge process.

Conclusion

In this article, we have discussed how to resolve merge conflicts in Git. By following these steps, you can easily resolve merge conflicts and keep your repository up-to-date. Remember, it is important to communicate with your team members and resolve merge conflicts as soon as possible to avoid any potential issues.
