Introduction

Git is an open-source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It is widely used in the software development industry for tracking changes in source code during the development process.

Basic Concepts

Before diving into the commands, it's important to understand some basic concepts of Git:

  • Repository: A repository is a collection of files and directories that are version controlled by Git.
  • Commit: A commit is a snapshot of the project at a particular point in time. Each commit has a unique identifier called a commit hash.
  • Branch: A branch is a separate line of development. You can create multiple branches to work on different features or bug fixes.
  • Merge: A merge combines changes from one branch into another.

Git Commands

Here are some essential Git commands you should know:

  • git init: Initialize a new Git repository.
  • git clone <repository-url>: Clone a repository from a remote server.
  • git add <file>: Stage changes to be committed.
  • git commit -m "<commit-message>": Commit staged changes.
  • git push: Push local commits to a remote repository.
  • git pull: Pull changes from a remote repository.

Branching and Merging

Branching and merging are fundamental to using Git effectively. Here's a brief overview:

  • Create a new branch: git checkout -b <branch-name>
  • Switch to a branch: git checkout <branch-name>
  • Merge branches: git merge <branch-name>

Advanced Techniques

Git offers a wide range of advanced techniques for managing your codebase. Some of the key ones include:

  • Stashing: Temporarily save the current changes and return to a previous state.
  • Git Hooks: Run custom scripts at various points in the Git workflow.
  • Submodules: Include other Git repositories as part of your project.
