How do you delete a branch in Git?
Vaibhav KothiaTo delete a branch in Git, use the following command:
git branch -d
For example, to delete the branch named “my_branch”, you would run the following command:
git branch -d my_branch
What is a branch in Git and how do you create one?
A branch in Git is an independent line of development that allows you to make changes to a project without affecting the original code. You can create a new branch by using the git branch command. For example, to create a branch called “my-new-branch”, you would run the following command:
git branch my-new-branch
What is a merge conflict and how do you resolve it?
A merge conflict occurs when two branches have changes that conflict with each other. This can happen when two people have made changes to the same file(s) on different branches.
For example, if two people have both made changes to the same line of code in the same file, and then try to merge the two branches, a conflict will occur.
To resolve a merge conflict, you must manually review the conflicting changes and decide which changes should be kept and which should be discarded. This can be done by using a version control system such as Git, which will provide a visual interface for comparing the conflicting changes. Once the changes have been reviewed and a decision has been made, the conflicts can be resolved by manually editing the file and committing the changes.
What is the difference between Git pull and Git fetch?
Git Pull: Git pull is used to fetch and download content from a remote repository and immediately update the local repository to match that content.
Example:
git pull origin master
This command fetches any new changes from the origin remote’s master branch and merges them into your local repository.
Git Fetch: Git fetch is used to fetch and download content from a remote repository but it doesn’t immediately update the local repository to match that content.
Example:
git fetch origin master
This command fetches any new changes from the origin remote’s master branch, but it doesn’t merge them into your local repository. You must explicitly merge the changes after fetching them.
How do you create a new local repository in Git?
1. Create a new directory on your local machine and open it in your terminal.
2. Initialize the directory as a Git repository by running the command `git init`.
3. Add your files to the repository by running the command `git add `.
4. Commit the changes to the repository by running the command `git commit -m “Initial commit”`.
5. Push the changes to the repository by running the command `git push origin master`.
How is Git different from other version control systems?
Git is a distributed version control system, meaning that the entire codebase and history is mirrored on every user’s computer. This allows developers to work independently and commit changes to their local repository without the need for a central server. This also allows for faster and more reliable version control, since developers can commit changes to their local repository and push them to the main repository when they are ready.
In contrast, other version control systems such as Subversion (SVN) are centralized. This means that all changes must be committed to a central server, which can be slow and unreliable. Additionally, since the codebase is stored in a single location, it is more vulnerable to data loss or corruption.
For example, if a developer using SVN makes a change to the codebase, they must commit it to the central server. If the server crashes or the connection is lost, the changes are not saved. With Git, the developer can commit the changes to their local repository and push them to the main repository when they are ready, ensuring that the changes are saved even if the connection is lost.
What is Git and why is it important?
Git is a version control system that allows developers to track changes to their code over time. It is important because it allows developers to collaborate on projects, keep track of changes, and identify any issues that may arise.
For example, if a developer is working on a project and makes a change to their code, they can commit the change to Git. This will allow other developers to see the change and review it before it gets merged into the main codebase. If there are any issues, they can be identified and fixed before the code gets released.
