Introduction

Git is a distributed version control system that helps you track changes in your code, collaborate with others, and maintain a history of your project. Git Bash is a terminal application for Windows that provides a Unix-like command-line experience for using Git.

This guide will walk you through setting up Git, using Git Bash, and mastering essential Git commands for local development.

Installation

Windows

Download Git for Windows from git-scm.comRun the installer with default options (or customize as needed)Git Bash will be installed automatically as part of the package

macOS

Install Git using Homebrew: brew install gitAlternatively, download from git-scm.com

Linux

For Debian/Ubuntu: sudo apt-get install gitFor Fedora: sudo dnf install gitFor other distributions, use the appropriate package manager

Verifying Installation

Open Git Bash (Windows) or Terminal (macOS/Linux) and type:

This should display the installed Git version.

Git Bash Basics

Git Bash provides a Unix-like shell experience on Windows. Here are some essential commands:

Navigation Commands

pwd – Print working directoryls – List files and directoriescd [directory] – Change directorymkdir [directory] – Create a new directoryrm [file] – Remove a filerm -r [directory] – Remove a directory and its contents

File Operations

touch [filename] – Create an empty filecat [filename] – Display file contentsnano [filename] or vim [filename] – Edit files in the terminal

Keyboard Shortcuts

Ctrl + C – Terminate the current commandCtrl + L – Clear the screenTab – Auto-complete commands or filenamesUp/Down arrows – Navigate through command history

Git Configuration

Before using Git, configure your identity:

Additional Configurations

Set your default editor:

Enable colorful output:

Basic Git Workflow

Initializing a Repository

Navigate to your project folder and initialize a Git repository:

Checking Status

See which files are tracked, modified, or staged:

Staging Files

Add files to the staging area:

Committing Changes

Save staged changes to the repository:

Or open an editor to write a more detailed commit message:

Viewing Commit History

Branching and Merging

Working with Branches

Create a new branch:

Switch to a branch:

Create and switch to a new branch in one command:

List all branches:

Merging Branches

Merge changes from another branch into your current branch:

Handling Merge Conflicts

When Git can’t automatically merge changes, you’ll need to resolve conflicts:

Git will mark the conflicted filesOpen the files and look for conflict markers (<<<<<<<, =======, >>>>>>>)Edit the files to resolve conflictsAdd the resolved files: git add <filename>Complete the merge: git commit

Deleting Branches

Delete a branch after merging:

Remote Repositories

Adding a Remote Repository

Viewing Remote Repositories

Pushing to a Remote Repository

Pulling from a Remote Repository

Cloning a Repository

Advanced Git Commands

Stashing Changes

Temporarily store modified files to work on something else:

Reverting Changes

Undo commits:

Reset to a previous state (use with caution):

Viewing and Comparing Changes

Interactive Rebase

Rewrite, squash, or reorder commits:

Troubleshooting

Common Issues and Solutions

Problem: “fatal: not a git repository”

Solution: Make sure you’re in the correct directory or initialize a repository with git init

Problem: Unable to push to remote repository

Solution:
Check if you have the correct permissionsPull latest changes first: git pull origin mainCheck if remote URL is correct: git remote -v

Problem: Merge conflicts

Solution: Resolve conflicts manually, then git add the resolved files and git commit

Problem: Accidental commit

Solution: Use git reset –soft HEAD~1 to undo the last commit while keeping changes

Git Best Practices

Commit frequently with clear, descriptive commit messagesCreate branches for new features or bug fixesPull before pushing to minimize conflictsWrite meaningful commit messages that explain why changes were madeUse .gitignore to exclude unnecessary files (build artifacts, dependencies, etc.)Review changes before committing with git diff and git statusKeep commits focused on a single logical changeUse tags for marking releases or important milestonesBack up your repositories regularlyDocument your Git workflow for team collaboration

.gitignore Example

Create a .gitignore file in your repository root:

Customize this file according to your project’s specific needs.

Conclusion

Git and Git Bash provide powerful tools for version control and collaborative development. In this guide, we covered installation across platforms, essential Git Bash commands, repository initialization, the core add-commit workflow, branching strategies, remote repository management, and advanced operations like stashing and rebasing. We also addressed common troubleshooting scenarios and best practices to maintain a clean workflow. With these fundamentals, you’re now equipped to track changes, collaborate effectively, and maintain a structured history of your projects.
