    Git is a distributed version control system that allows multiple developers to collaborate on a project, tracking changes made to the source code.

  2. Explain the difference between Git and GitHub.

    Git is the version control system, while GitHub is a web-based platform for hosting Git repositories and collaborating with others.

  3. How do you install Git on your local machine?

    You can download and install Git from the official website (https://git-scm.com/). Follow the installation instructions for your specific platform.

  4. What is a Git repository?

    A Git repository is a directory where Git tracks and manages the history of files. It contains the project’s source code and all the version history.

  5. How do you initialize a Git repository?

    To initialize a Git repository in a directory, use the git init command:

    bash
    git init
  6. What is a commit in Git?

    A commit is a snapshot of the repository at a specific point in time. It represents a set of changes made to the codebase.

  7. How do you create a new commit?

    To create a new commit with your changes, use the following commands:

    bash
    git add . # Stage your changes
    git commit -m "Your commit message" # Create a new commit
  8. What is the Git staging area (index)?

    The staging area is where you prepare changes before committing them. You use git add to stage changes.

  9. Explain the Git workflow in a basic project.

    The typical Git workflow includes the following steps:

    • Modify files in your working directory.
    • Stage changes using git add.
    • Commit changes using git commit.
    • Push changes to a remote repository using git push (in a collaborative project).

Git Commands and Operations

  1. What is the purpose of the git clone command?

    git clone is used to create a copy of a remote Git repository on your local machine.

    bash
    git clone <repository_url>
  2. How do you check the status of your working directory in Git?

    Use the git status command to see the status of your working directory, including tracked and untracked files.

    bash
    git status
  3. Explain the difference between git add . and git add -A.
    • git add . stages all changes in the current directory and its subdirectories.
    • git add -A stages all changes, including deletions and new files, in the entire repository.
  4. What is the purpose of the git log command?

    git log displays a history of commits in the repository, including author information, dates, and commit messages.

    bash
    git log
  5. How do you create and switch to a new Git branch?

    To create and switch to a new branch, use the git checkout -b command:

    bash
    git checkout -b <branch_name>
  6. How do you merge one Git branch into another?

    Use the git merge command to merge changes from one branch into another:

    bash
    git checkout <target_branch>
    git merge <source_branch>
  7. Explain what a Git conflict is and how to resolve it.

    A Git conflict occurs when two branches have made conflicting changes to the same file. To resolve a conflict:

    • Open the conflicted file.
    • Manually resolve the conflicting changes.
    • Add the resolved file to the staging area using git add.
    • Commit the resolved changes.
  8. What is Git rebase, and how is it different from merge?

    Git rebase is used to incorporate changes from one branch into another by moving or combining commits. Unlike merge, rebase creates a linear commit history.

    bash
    git checkout <feature_branch>
    git rebase <main_branch>
  9. How do you undo the last Git commit?

    To undo the last commit without losing the changes, you can use git reset:

    bash
    git reset HEAD~1

    This command resets the branch pointer to the previous commit, leaving your changes unstaged.

  10. What is Git cherry-pick, and when would you use it?

    Git cherry-pick is used to apply a specific commit from one branch to another. It’s useful for selectively bringing changes from one branch to another.

    bash
    git cherry-pick <commit_hash>
  11. Explain Git tags and how to create and list them.

    Git tags are references to specific commits. To create a tag, use git tag:

    bash
    git tag <tag_name>

    To list tags:

    bash
    git tag
  12. What is the purpose of the .gitignore file?

    The .gitignore file specifies files and directories that should be ignored by Git. It’s used to exclude build artifacts, temporary files, and other items from version control.

    Example .gitignore file:

    plaintext
    # Ignore compiled files
    *.class
    *.jar

    # Ignore log files
    *.log

    # Ignore build output directories
    /build/
    /dist/

Collaboration and Remote Repositories

    Use the git push command to send your local changes to a remote repository:

    bash
    git push origin <branch_name>
  2. What is the purpose of the git pull command?

    git pull fetches changes from a remote repository and merges them into the current branch:

    bash
    git pull origin <branch_name>
  3. How do you fetch changes from a remote repository without merging?

    To fetch changes without merging, use git fetch:

    bash
    git fetch origin
  4. What is a Git remote?

    A Git remote is a reference to a remote repository. Common remote names include origin (the default remote created when cloning) and others for collaboration.

  5. How do you create a new remote in Git?

    You can add a remote repository using git remote add:

    bash
    git remote add <remote_name> <repository_url>
  6. Explain the difference between git fetch and git pull.
    • git fetch downloads changes from a remote repository but does not automatically merge them.
    • git pull fetches and merges changes in one step.
  7. What is a Git fork, and how does it differ from a clone?

    A Git fork is a copy of a repository on GitHub or another Git hosting platform. It allows you to make changes independently and propose them as pull requests to the original repository. Cloning creates a local copy of a repository on your machine.

  8. How do you resolve conflicts in a pull request on GitHub?

    To resolve conflicts in a pull request on GitHub:

    • Click on the pull request.
    • Click the “Resolve conflicts” button.
    • Resolve conflicts in the GitHub editor.
    • Commit the changes.
    • Complete the pull request.

Git Branching and Workflow

  1. Explain the purpose of long-running branches like main or master.

    Long-running branches like main or master typically represent the stable and production-ready version of the code. Developers create feature branches to work on new features and merge them into main when they are ready.

  2. What is the purpose of feature branches in Git?

    Feature branches are used to isolate work on a specific feature or bug fix. They are created from the main or develop branch and merged back when the feature is complete.

  3. Explain the concept of Gitflow.

    Gitflow is a branching model that defines a structured workflow for Git repositories. It involves two main branches, main and develop, along with feature, release, and hotfix branches. It helps manage releases and maintain a stable main branch.

  4. What is the purpose of a hotfix branch in Gitflow?

    A hotfix branch is used to address critical issues in the production codebase. It allows for quick fixes that can be applied to the main branch without disrupting ongoing development.

  5. What is rebasing in Git, and when would you use it?

    Rebasing is the process of moving or combining commits onto a different base commit. It’s used to maintain a linear commit history and is often used when working with feature branches.

  6. Explain Git squash and how to squash commits.

    Git squash combines multiple commits into a single commit with a descriptive commit message. To squash commits, use an interactive rebase:

    bash
    git rebase -i HEAD~n

    Replace n with the number of commits you want to squash.

  7. What is a Git hook, and how can you use it in a repository?

    A Git hook is a script that runs at specific points in Git’s execution. You can use hooks to automate tasks like linting, testing, or enforcing code conventions. Hooks are stored in the .git/hooks directory of a Git repository.
