Its pervasive adoption is evidenced by a user base exceeding 40 million individuals worldwide, a testament to its unparalleled efficacy. Beyond its core function of meticulously tracking code history, Git integrates seamlessly with crucial development lifecycle components such as task orchestration and sophisticated bug detection mechanisms. This confluence of features solidifies Git’s standing as an exceptionally potent and indispensable technology, embraced by a vast majority of industry experts and development teams. Through rigorous analytical discourse and meticulous research, we have meticulously curated the subsequent compendium of Git interview inquiries, designed to thoroughly assess a candidate’s theoretical comprehension and practical dexterity across various levels of expertise, from foundational principles to advanced paradigms.

Foundational Inquiries into Git Principles

Understanding the core mechanics of Git is paramount for any aspiring or seasoned developer. These fundamental questions probe a candidate’s grasp of Git’s basic operations and conceptual underpinnings.

Repository Genesis: Initiating a Git Project

Question: Elucidate the procedural steps involved in the creation of a new repository within the Git environment.

Answer: To inaugurate a fresh repository in Git, the command git init is invoked. The execution of this directive meticulously constructs a hidden .git directory within the designated project directory. This .git subdirectory serves as the central repository for all version control metadata, encompassing object databases, references to commits, and configuration parameters, thus enabling Git to commence tracking the project’s evolution. It acts as the profound nucleus of the version control system for that specific project.

The Concept of ‘Origin’ in Remote Repositories

Question: Define the term «origin» within the context of Git’s distributed architecture.

Answer: In Git parlance, «origin» functions as a conventional alias, serving as a mnemonic shorthand for the remote repository from which a local project was initially cloned. Rather than perpetually referencing the remote repository’s full Uniform Resource Locator (URL), «origin» provides an elegant and concise means of referencing this upstream source. This convention significantly streamlines commands pertaining to fetching, pushing, and pulling, thereby enhancing legibility and operational efficiency in multi-developer environments. It typically points to the primary, shared version of the repository.

Pushing Changes: Uploading to the Remote Repository

Question: Articulate the primary function of the git push command.

Answer: The git push command is exclusively employed for the meticulous transference of local repository content—comprising commits, branches, and tags—to a designated remote repository. This operation effectively synchronizes the local development progress with the shared, central codebase. Prudence is paramount when utilizing git push, as injudicious application, particularly forceful pushes (—force), carries the inherent risk of irrevocably overwriting or obliterating historical changes on the remote, necessitating its cautious and informed deployment.

Pulling Changes: Integrating Remote Content Locally

Question: Describe the utility of the git pull command.

Answer: The git pull command orchestrates a dual-phase operation: it first fetches (downloads) content—including commits, files, and references—from a specified remote repository, and subsequently merges this newly acquired data with the current local branch. This amalgamation aims to seamlessly integrate the remote modifications into the local working directory, ensuring that the developer’s environment is synchronized with the latest upstream advancements. It is the primary mechanism for receiving updates from the collaborative codebase.

Differentiating Rebase and Merge: Divergent Integration Strategies

Question: Expound upon the fundamental distinctions between git rebase and git merge.

Answer: The core divergence between git rebase and git merge lies in their respective approaches to integrating changes from one branch into another. Git rebase effectively re-applies the commits of a feature branch onto a new base tip, typically the master or main branch. This process results in a linear project history, making it appear as though development occurred sequentially, without explicit merge commits. Conversely, git merge preserves the complete historical lineage by introducing a new «merge commit» that explicitly records the integration point of two divergent branches. While rebase maintains a cleaner, linear history, merge retains a more explicit record of all branching and merging activities.

The Imperative of Branching in Git

Question: Justify the necessity of branching within the Git version control system.

Answer: Branching in Git is a foundational construct that offers unparalleled flexibility and isolation in development workflows. It allows developers to create independent lines of development (branches) from a central codebase, fostering a sandbox environment where new features can be prototyped, bugs can be rectified, or experimental changes can be implemented without impinging upon the stability or integrity of the main project line. This mechanism facilitates parallel development efforts, enabling multiple contributors to work concurrently on disparate aspects of a project. Moreover, branching permits the seamless traversal between various states of the codebase, allowing developers to revert to previous work configurations while simultaneously preserving the integrity of recent, in-progress modifications, thereby enhancing productivity and mitigating risk.

Git vs. GitHub: A Definitive Demarcation

Question: Delineate the key differences between Git and GitHub.

Answer: Git and GitHub, while intrinsically linked in the modern development ecosystem, represent distinct entities. Git is an open-source, distributed version control system (DVCS) software that operates locally on a developer’s machine. Its primary function is the meticulous management and tracking of source code history, enabling individual developers or teams to monitor changes, revert to previous versions, and manage parallel development lines without reliance on a central server. GitHub, conversely, is a web-based, cloud-hosted platform that provides management services for Git repositories. It extends Git’s core functionalities by offering a graphical interface, robust collaboration features (like pull requests, issue tracking, and code review tools), and centralized repository hosting. Essentially, Git is the underlying technology for version control, while GitHub is a popular service that leverages Git to facilitate large-scale collaboration and project management, particularly for open-source initiatives.

Branch Creation: Forging New Development Paths

Question: Articulate a method for initiating a new branch within Git.

Answer: To instantiate a new branch in Git, the command git branch <new-branch-name> is employed. This command creates a new reference pointing to the current commit, effectively establishing a new line of development. To immediately switch to this newly created branch, the git checkout <new-branch-name> command is subsequently utilized. For a more concise, single-step operation that both creates and switches to a new branch, the git checkout -b <new-branch-name> command proves exceedingly efficient.

The Purpose of the .gitignore File

Question: Explain the fundamental purpose of the .gitignore file.

Answer: The .gitignore file is a plain text configuration file that instructs Git to intentionally disregard certain files or directories when tracking changes within a repository. Its primary purpose is to prevent the accidental or unnecessary inclusion of transient files (e.g., compiled binaries, log files, temporary build artifacts, editor-specific configuration files, personal IDE settings, or sensitive credentials) that are not intrinsic to the project’s source code and should not be committed to the version history. By listing these patterns in .gitignore, developers ensure a cleaner repository, reduce clutter, and avoid committing machine-generated files that vary across different development environments.

Cloning a Specific Branch from a Repository

Question: Detail the procedure for cloning a particular branch from a Git repository.

Answer: To acquire a local copy of a specific branch from a remote Git repository without cloning the entire repository’s history, the git clone command is augmented with the branch-specifying flag. The precise syntax is: git clone -b <branch-name> <repository-url>. This command instructs Git to fetch only the history pertinent to the <branch-name> and set up the local repository with that branch checked out, optimizing for bandwidth and local storage when only a subset of the remote content is required.

Renaming a Local Git Branch

Question: Describe the method for renaming a local Git branch.

Answer: To effect a change in the nomenclature of a local Git branch, the git branch -m <old-name> <new-name> command is utilized. This command renames the branch without affecting its history or contents. If the user is currently positioned on the branch that requires renaming, a more concise form can be employed: git branch -m <new-name>. This operation solely modifies the local branch reference, requiring a subsequent git push —set-upstream origin <new-name> (and potentially a git push origin :<old-name>) to reflect the change on the remote repository.

Identifying Modified Files in a Specific Commit

Question: How does one ascertain a list of files that underwent modification within a particular commit?

Answer: To retrieve an enumeration of files that were altered or introduced in a specific commit, the git show —name-only <commit-hash> command is employed. The <commit-hash> represents the unique SHA-1 identifier of the commit in question. The —name-only flag restricts the output to display only the names of the files affected by that commit, rather than presenting the full diff, providing a concise summary of the committed changes.

Removing a File from the Staging Area

Question: Outline the process for removing a file from Git’s staging area.

Answer: To unstage a file—effectively moving it from the staging area (also known as the index) back to the working directory without discarding any modifications—the command git reset HEAD <file-path> is executed. This command specifically targets the specified file, instructing Git to remove it from the next commit snapshot while preserving its content in the working tree. For unstaging all files, git reset HEAD (without a file path) can be used.

Inherent Advantages of Utilizing Git

Question: Enumerate the salient advantages associated with the adoption of Git.

Answer: Git offers a multitude of compelling advantages that have cemented its status as the industry-standard version control system:

• Distributed Architecture: Each developer possesses a complete copy of the entire repository history, enabling robust data redundancy and ensuring high availability. If the central server becomes unavailable, development can continue locally.
• Offline Capability: Developers can commit, branch, merge, and review history entirely offline, as all necessary repository data resides locally. This dramatically enhances productivity, particularly in environments with unreliable network connectivity.
• Exceptional Performance: Written in C, Git is remarkably fast, excelling in handling large repositories and complex histories with superior network performance and optimized disk utilization.
• Seamless Collaboration: Git’s branching and merging model facilitates highly concurrent and collaborative development. Features like pull requests (on platforms like GitHub) streamline code review and integration processes.
• Scalability: It is eminently suitable for projects of virtually any scale, from small individual endeavors to sprawling enterprise-level applications involving thousands of contributors.
• Data Integrity: Git employs cryptographic SHA-1 hashes to uniquely identify and secure every object (files, commits, trees), guaranteeing that the history cannot be silently altered.
• Flexibility: It supports a wide array of workflows (e.g., centralized, feature branch, Gitflow) that can be tailored to specific team dynamics and project requirements.

These inherent benefits collectively render Git an exceptionally powerful and adaptable tool for modern software development.

Distinguishing git init from git clone

Question: Articulate the core difference between the git init and git clone commands.

Answer: The fundamental distinction between git init and git clone lies in their respective initialization contexts. The git init command is employed to create a brand-new, empty Git repository within the current directory (or a specified directory). It transforms an existing, untracked project folder into a Git-managed repository, ready for initial commits. Conversely, the git clone command is utilized to create a local copy of an existing Git repository, typically residing at a remote location (e.g., on GitHub, GitLab, or a private server). git clone not only copies the entire history of the remote repository but also automatically sets up remote tracking branches and checks out the default branch, preparing the local environment for immediate collaboration.

The Role of a .gitkeep File

Question: What is the specific purpose of a .gitkeep file?

Answer: It is important to clarify that .gitkeep is not an intrinsic Git feature or command. Instead, it is a conventional filename adopted by developers to work around a particular characteristic of Git: Git does not track empty directories. If a developer wishes to commit and track an otherwise empty folder (for example, a placeholder for future logs, uploads, or configuration files), they create a dummy file named .gitkeep (or any other arbitrary file) within that directory. This provides Git with a file to track, thereby ensuring that the empty directory structure is preserved in the repository’s history and propagates to other collaborators upon cloning or pulling.

Utility of the git diff Command

Question: Explain the practical application of the git diff command.

Answer: The git diff command is an indispensable tool for visually inspecting, comparing, and understanding changes within a project’s codebase. It manifests the differences between various states of the repository, such as between the working directory and the staging area, between the staging area and the last commit, between two different commits, or between two distinct branches. By displaying line-by-line additions, deletions, and modifications, git diff provides a granular overview of what has been altered, enabling developers to review their work, prepare commits, or analyze historical changes with precision before integration.

Understanding Git Bash

Question: Provide a brief explanation of Git Bash.

Answer: Git Bash is a robust application package designed primarily for Windows operating systems that provides a command-line interface (CLI) environment emulating the Unix-like shell experience. It bundles the Bash shell (Bourne Again SHell), the Git version control system itself, and a selection of commonly used Unix utilities (such as ls, mv, cp, grep, ssh) that are otherwise unavailable natively on Windows. Git Bash enables Windows users to interact with Git and manage their repositories through familiar command-line paradigms, providing a powerful alternative to graphical user interfaces for Git operations and offering a more complete development environment.

The Objective of the git clean Command

Question: What is the explicit purpose of the git clean command?

Answer: The git clean command is specifically engineered to remove untracked files from the working directory. Untracked files are those that exist in the working directory but are not staged for commit and are not ignored by the .gitignore file. This command is typically employed to tidy up a working directory, removing temporary build artifacts, generated files, or other extraneous items that might accumulate during development but should not be part of the repository. It offers options (-f for force, -n for dry run, -d for directories) to control the scope and safety of the cleanup operation.

Tagging in Git: Marking Milestones

Question: Describe the concept of «tagging» in Git.

Answer: Tagging in Git serves as a mechanism to mark significant points in a project’s history, typically release points (e.g., v1.0, v2.1-beta). A tag is essentially a permanent, immutable pointer to a specific commit. Unlike branches, which are mutable and evolve, tags are static snapshots. This allows developers to assign human-readable names to critical checkpoints, making it effortless to reference a particular version of the codebase. Instead of obscure commit IDs, clear tag names can be utilized when checking out specific commits or pushing these designated milestones to a remote repository, providing a stable reference for historical versions.

Forking in Git: Independent Project Experimentation

Question: Explain the concept of «forking» in Git.

Answer: Forking, within the context of Git (particularly prevalent on hosting platforms like GitHub), refers to the creation of a personal copy of an existing remote repository under one’s own account. A fork is a server-side clone of the original project. The primary motivation for forking is to enable a developer to experiment with changes, implement new features, or rectify issues without directly impacting or endangering the integrity of the original, upstream project. This isolation is ideal for proposing modifications to someone else’s project; once changes are deemed satisfactory in the fork, they can be submitted back to the original repository via a pull request for review and potential integration.

The «Index» or «Staging Area» in Git

Question: Define the terms «Index» or «Staging Area» in Git.

Answer: The «Index» or «Staging Area» in Git represents an intermediate, conceptual layer positioned between the working directory (where files are actively being modified) and the local repository (where commits are stored). It serves as a meticulously crafted snapshot of the next commit. When changes are made in the working directory, they are first added to the staging area using git add. This allows developers to selectively group related changes from multiple files into a single, coherent commit, fine-tuning what changes will be included. This intermediate area provides an opportunity to review, format, and prepare modifications before they are permanently recorded in the project’s commit history, ensuring that each commit is atomic and meaningful.

Programming Language Underlying Git

Question: Identify the programming language utilized in the development of Git.

Answer: Git is predominantly implemented using the C programming language. This architectural choice contributes significantly to Git’s renowned performance, ensuring that core operations are executed with minimal computational overhead and maximal efficiency, which is crucial for handling large repositories and complex versioning tasks. The use of C allows for close-to-metal optimization, providing a robust and performant foundation for a distributed version control system.

Duplicating a Local Branch

Question: Outline the method for creating a copy of an existing local branch.

Answer: To create an exact duplicate of an existing local branch, the command git checkout -b <new-branch-name> <existing-branch-name> is employed. This command first creates a new branch named <new-branch-name> and then immediately switches the active branch to this newly created duplicate. The content and history of the <new-branch-name> will be identical to that of the <existing-branch-name> at the point of creation, providing a fresh working context without altering the original branch.

Git Inquiries for Budding Developers

These questions are geared towards candidates who are relatively new to Git but possess a foundational understanding, focusing on practical problem-solving and common workflows.

Navigating Merge Conflicts in Git

Question: Detail the procedure for resolving a conflict in Git.

Answer: When Git is unable to automatically integrate divergent changes from two branches during a merge or rebase operation, a «merge conflict» arises. The resolution process entails several steps:

• Identification: Git will notify the user of conflicting files, marking them in the working directory (often with <<<<<<<, =======, >>>>>>> markers).
• Manual Editing: The developer must manually edit each conflicting file, removing the conflict markers and carefully integrating the desired changes from both conflicting versions into a unified, correct state.
• Staging Resolution: After resolving all conflicts within a file, the modified file must be explicitly added to the staging area using git add <file-path>. This signals to Git that the conflicts for that file have been addressed.
• Committing the Resolution: Once all conflicting files are staged, the final step is to create a new commit to record the resolution. This is achieved by running git commit. Git will automatically generate a default merge commit message, which can be accepted or customized.

This meticulous process ensures that conflicting changes are reconciled correctly, preserving the project’s integrity.

Understanding Git Repositories and Hosting Services

Question: Define a Git repository and enumerate some prevalent Git hosting services.

Answer: A Git repository (often abbreviated as «repo») fundamentally constitutes a collection of files, along with the complete history of their revisions, associated metadata, and configuration settings, all meticulously tracked by the Git version control system. It serves as a central database for all changes made to a project, enabling developers to revert to past states, track modifications, and collaborate seamlessly. These files and their histories are typically «cloned» from remote repositories onto users’ local machines for further modifications and updates.

Several widely adopted platforms provide robust Git hosting services, extending Git’s local capabilities to a collaborative, cloud-based environment:

• GitHub: Widely recognized as the largest and most popular code-hosting platform, renowned for its extensive community and collaborative features.
• GitLab: Offers a comprehensive DevOps platform, encompassing Git repository management, CI/CD pipelines, and security features, available both as a cloud service and an on-premises solution.
• Bitbucket: Known for its strong support for private repositories and its integration with Jira and Trello, making it popular among enterprise teams.
• SourceForge: A long-standing platform offering open-source project hosting, including Git repositories, alongside various other development tools.

These services play a crucial role in modern distributed development workflows.

Git and GitHub: A Symbiotic Relationship Revisited

Question: Elaborate on the relationship between Git and GitHub.

Answer: Git is a free, open-source, and distributed version control system (DVCS) that was originally engineered by Linus Torvalds to efficiently and rapidly manage projects of all scales, particularly the Linux kernel. It is a command-line tool and a set of protocols for tracking changes in source code. GitHub, conversely, is a highly popular, internet-based hosting service and web-based platform that utilizes Git as its underlying version control engine. It augments Git’s distributed version control and source code management functionalities with a rich array of collaborative features such as web-based code review, issue tracking, wikis, project management tools, and social networking features for developers. Essentially, Git provides the powerful version control mechanics, while GitHub provides a centralized, cloud-based social and collaborative wrapper around Git repositories, facilitating large-scale open-source and private development.

Cherry-Picking in Git: Selective Commit Application

Question: Explain the operation of git cherry-pick.

Answer: Git cherry-pick is a potent command that enables the selective application of an arbitrary Git commit from one branch onto another branch, by its reference (commit hash). Unlike a full merge or rebase, which integrate entire sequences of commits, cherry-pick allows for the precise selection and application of individual commits. This functionality is particularly useful in scenarios where a specific fix or feature developed on one branch needs to be incorporated into another branch without merging the entire feature branch. It essentially creates a new commit on the target branch that replicates the changes introduced by the picked commit, making it a valuable tool for back-porting fixes or selectively undoing certain changes on a specific line of development.

Distinguishing git fetch from git pull

Question: Differentiate between the git fetch and git pull commands.

Answer: The distinction between git fetch and git pull is fundamental to managing remote repositories effectively. Git fetch is a less destructive operation: it retrieves new data (commits, branches, tags) from a designated remote repository and updates the local remote-tracking branches, but it does not integrate these changes into the current local working files or branch. It merely downloads what’s new, allowing the user to review the changes before deciding how to incorporate them. This provides a safe way to check for upstream updates without altering the current local work.

Conversely, git pull is a composite command that executes two sequential operations: it first performs a git fetch to retrieve new data from the remote, and then it immediately attempts to merge (or sometimes rebase, depending on configuration) those newly fetched changes into the current local branch. This direct integration means that git pull automatically updates the HEAD of the current branch with the latest remote changes and applies them to the working copy files. While convenient, git pull carries the potential risk of merge conflicts if local changes clash with remote updates, necessitating immediate resolution. Fetch is about observation; pull is about action and integration.

Understanding git checkout

Question: Elucidate the functionality of git checkout in Git.

Answer: The git checkout command is a versatile and fundamental Git operation with multiple uses, primarily centered around navigating and manipulating the working directory and HEAD pointer. Its core functionality involves switching the current HEAD to point to a different branch, commit, or specific file.

• Branch Switching: When used with a branch name (e.g., git checkout feature-branch), it updates the working directory to match the state of that branch and moves the HEAD to point to it, making it the active branch for further development.
• Restoring Files: It can be used to restore specific files to their state at a particular commit (e.g., git checkout <commit-hash> — <file-path>) or to their state in the last commit on the current branch (git checkout — <file-path>). This is invaluable for discarding local modifications to individual files.
• Checking Out Commits: By specifying a commit hash (git checkout <commit-hash>), it places the repository into a «detached HEAD» state, allowing examination of the project at a historical point without being on a branch. This is useful for inspection or debugging historical states.

In essence, git checkout acts as a crucial navigational and restorative tool, allowing developers to move between different versions of their project.

The Purpose of git rebase

Question: What is the primary function of git rebase?

Answer: Git rebase is an advanced Git command primarily used for reapplying a series of commits from one branch on top of another base branch. Conceptually, it takes the entire commit history of a feature branch and «moves» it to begin at a different commit point, typically the tip of the master or main branch. This process rewrites the project history by creating new commit objects for the rebased commits. The key outcome of rebase is a linear project history, which can be aesthetically cleaner and easier to read than a history cluttered with numerous merge commits. It is often considered an alternative to git merge for integrating changes, as it avoids creating a merge commit and makes it appear as if the development on the feature branch occurred directly on top of the target branch’s latest commit.

The «Undo» Operation: git revert

Question: Explain the purpose and operation of git revert.

Answer: Git revert is a «forward-moving undo» operation in Git. Unlike git reset, which effectively erases history by moving the branch pointer to an earlier commit, git revert creates a new commit that precisely reverses the changes introduced by one or more previous commits. This means the original commits remain intact in the project history, and a new commit is added that undoes their effect. This characteristic makes git revert a safe and non-destructive way to undo changes, especially when dealing with commits that have already been pushed to a shared remote repository, as it preserves the integrity of the collaborative history by not rewriting it. It is particularly useful for public branches where history immutability is crucial.

Resetting vs. Reverting: Distinct Approaches to Undoing Changes

Question: Delineate the differences between git reset and git revert.

Answer: The distinction between git reset and git revert lies in their impact on the repository’s history. Git reset is a powerful command primarily used for undoing changes by moving the HEAD pointer (and optionally the branch pointer) to a previous commit. Depending on the mode (e.g., —soft, —mixed (default), —hard), git reset can unstage changes, discard local modifications, or even completely erase commits from the branch’s history. Crucially, git reset rewrites history by abandoning subsequent commits, making it generally unsuitable for commits that have already been pushed to shared remote repositories because it creates inconsistencies for other collaborators.

Conversely, git revert is a «safe undo» operation. Instead of rewriting history, git revert creates a new commit that introduces changes that are the exact inverse of the changes in the target commit. The original commit remains in the history, and the new «reverting» commit is added on top. This makes git revert ideal for undoing changes on public or shared branches, as it does not rewrite history and therefore avoids disrupting collaborators’ local repositories. In essence, reset rewrites, revert adds a new, undoing commit.

git remote versus git clone: Managing Remote Connections

Question: What is the difference between git remote and git clone?

Answer: The commands git remote and git clone serve different but related purposes concerning remote repositories. Git clone is used to create an initial local copy of an entire existing remote repository, including its full history, all branches, and tags. When git clone is executed, it automatically sets up a «remote» named origin that points back to the original remote repository, and it checks out the default branch.

In contrast, git remote is used to manage the set of remote connections after a repository has been initialized or cloned. Specifically, git remote add <name> <url> adds a new remote repository reference to an existing local Git repository, allowing it to track or interact with another upstream source beyond the initially cloned origin. git remote -v lists existing remotes. git remote doesn’t fetch any code itself; it merely manages the symbolic names and URLs for other remote repositories that your local repository can interact with for fetching, pushing, or pulling.

Understanding Git Stash

Question: Define the concept of git stash.

Answer: Git stash is an exceptionally useful command that allows developers to temporarily set aside (or «stash») changes made to their working directory and staging area, effectively creating a clean working state, without needing to commit those in-progress changes. When git stash is executed, Git takes all modified tracked files and staged changes, saves them onto a stack, and then reverts the working directory to the state of the last HEAD commit. This is invaluable when a developer is in the midst of a task, has uncommitted changes, but urgently needs to switch branches to address a hotfix, pull upstream changes, or work on another unrelated task, and then seamlessly return to their previous work later without losing progress or polluting the commit history with incomplete work. It provides a clean slate while preserving the current edits for future reapplication.

Disposing of Stashed Items: git stash drop

Question: What is the function of git stash drop?

Answer: The git stash drop command is utilized to remove a specific stashed item from the stash list. When a developer no longer requires a particular set of stashed changes, or once those changes have been successfully applied and integrated elsewhere, git stash drop can be used to clean up the stash stack. By default, executing git stash drop (without arguments) removes the most recently stashed item. Alternatively, to remove a specific item from the stack, its stash index can be provided as an argument (e.g., git stash drop stash@{2}), ensuring precise management of the stashed changes.

Identifying Merged Branches

Question: How does one determine if a particular branch has been merged into the master (or main) branch?

Answer: Git provides convenient commands to ascertain the merge status of branches:

• git branch —merged <branch-name>: This command, when given a specific branch name (e.g., master or main), will list all local branches that have had their content fully integrated into the specified branch. For example, git branch —merged master displays all branches whose history is fully contained within the master branch.
• git branch —merged: Executed without any arguments, this command lists all branches that have been merged into the current HEAD (the branch you are currently on).
• git branch —no-merged: This command lists all local branches that have not yet been merged into the current HEAD (or a specified branch, if an argument is provided). These branches contain unique commits that are not present in the target branch’s history, indicating ongoing work or unintegrated features.

These commands are invaluable for repository cleanup and understanding branch relationships.
