Differentiate Between Git Merge and Git Rebase

Assume youre working on a new feature in a dedicated branch, and another team member pushes new commits to the master branch.Â

Merge is used to incorporate new commits into your feature branch. Every time you need to include modifications, this requires an extra merging commit. It taints the history of your feature branch.

You can rebase the feature branch into master instead of merging it. This incorporates all the new commits in the master branch. It also re-writes the project history by creating brand new commits for each commit in the original branch.

What is a Merge Conflict in Git and how can it be resolved?

When you have merging branches with opposing commits, a merge conflict occurs, and Git needs your help to select which changes to include in the final merge.

When competing for line changes, i.e. when users make different modifications to the same line of the same file on different branches in your Git repository, this is done to avoid merging conflicts.

Step 1: Under your repository name, click Pull requests.Â

Step 2: Click the pull request with the merge conflict youd like to resolve in the “Pull Requests” list. Click Resolve conflicts near the bottom of your pull request.

Step 3: Decide whether you want to maintain just your branchs changes, only the other branchs changes, or make a completely new modification that includes both branches changes.Â

Step 4: Delete the conflict markers and make the changes you want in the final merge.Â

Step 5: If your file has over one merge conflict, scroll down to the next set of conflict markers and repeat steps four and five to resolve the issue. Mark the file as resolved once youve resolved all the conflicts.

Step 6: If you have more than one file with a conflict, go to the left side of the screen and select the next file you wish to edit under “conflicting files”. Then repeat the above steps until youve resolved all the merge conflicts in your pull request.

Step 7: Click Commit merge once youve resolved all of your merge conflicts. It merges the entire base branch into your head branch as a result of this. Click Merge pull request to combine your pull requests.

Resolve the issue with a local clone of the repository and commit the update to your GitHub branch.

It resolves all other forms of merge conflicts using this method. To push the update, you can use the command line or a program like GitHub desktop.

Step1: Open Git Bash. Go to the local Git repository where the merge conflict exists.

Step2: Make a list of the files that have been affected by the merge dispute. In this case, there is a merge conflict in the file

Step 3: Navigate to the file with merge conflicts in any text editor, such as Sublime Text or Atom. Look for the conflict marker “<<<<<<" if you want to see where the merging conflict started in your file.

After the line “<<<<<

Step 4: Next you’ll see =======, which divides your changes from the changes in the other branch, followed by >>>>>>> BRANCH-NAME

Step 5: Decide whether you want to simplt maintain your branchs changes, only the other branchs changes, or make a completely new modification that includes both branches changes.

Step 6: Delete the conflict markers, <<<<<, =====, >>>>> and make changes you want in the final merge.Â

Step 7: Add or stage your changes. Commit your changes with a comment.Â

You may now combine the branches using the command line, or you can upload your changes to your GitHub remote repository and merge them in a pull request.
