What Does `Git Merge Origin` Do?

4 minutes read

git merge origin is a command used in Git to merge changes from a remote repository (usually called "origin") into the current local branch. This command fetches the changes from the remote repository and combines them with the changes in the current local branch. It is commonly used to synchronize the local branch with the changes made by other team members in the remote repository.


What is the purpose of the HEAD pointer in git?

The HEAD pointer in Git is a reference to the currently checked out commit or branch in the repository. It points to the branch or commit that is currently being worked on, serving as a reference point for the next commit that will be added to the repository. The HEAD pointer is used to keep track of the current state of the repository and is crucial for navigating between different branches and commits in the repository.


What is the role of the .gitignore file in git?

The .gitignore file is a configuration file used in Git to specify which files and directories should be ignored and not tracked by Git. This file helps in avoiding the unnecessary tracking of files such as build artifacts, temporary files, configuration files, and other files that do not need to be included in the repository. By specifying patterns in the .gitignore file, Git will automatically ignore these files and they will not be included in the repository when you commit changes. This helps keep the repository clean and focused only on the essential files needed for the project.


What is the difference between a local and remote git repository?

A local git repository is a repository that is stored on your local machine, usually in a designated folder on your computer. This allows you to work on your code, commit changes, and manage versions locally without needing an internet connection.


On the other hand, a remote git repository is hosted on a remote server, such as GitHub, GitLab, or Bitbucket. This allows you to push changes from your local repository to the remote repository, collaborate with others by sharing your code, and access your code from different machines.


In summary, the main difference between a local and remote git repository is where the repository is stored and how it is accessed and shared with others.


How to squash commits in git?

To squash commits in Git, you can use the git rebase command. Here's how you can squash the last 3 commits in your current branch:

  1. Open your terminal and navigate to your Git repository.
  2. Run the following command to start an interactive rebase session for the last 3 commits:
1

git rebase -i HEAD~3


  1. This will open a text editor with a list of the last 3 commits. Change pick to squash for all the commits except the first one (which you want to keep as is).
  2. Save and close the editor. Git will then squash the selected commits into one. If there are any conflicts, you will need to resolve them before completing the rebase.
  3. Once the rebase is complete, you can push the changes to your remote repository using: 
1

git push --force


Keep in mind that using --force will rewrite the commit history, so make sure to communicate with your team before force pushing changes.


What is the significance of the origin keyword in git?

In Git, the "origin" keyword refers to the default name given to the remote repository from which the local repository was cloned. It serves as a reference to the remote repository and is used to fetch changes from or push changes to the remote repository.


The significance of the "origin" keyword in Git is that it helps to streamline the process of collaborating on projects with others, as it simplifies the process of fetching and pushing changes to a shared central repository. It allows developers to easily synchronize their local repository with the remote repository, making it easier to work on the same codebase with others and keeping track of changes made by different team members.


What is the purpose of the cherry-pick command in git?

The purpose of the cherry-pick command in git is to apply a specific commit from one branch onto another branch. This allows developers to selectively choose which changes or commits they want to include in a different branch, without merging the entire history of one branch into another. This can be useful for incorporating specific bug fixes, features, or changes from one branch to another, without affecting the entire project's history.
