**Course Title:** Version Control Systems: Mastering Git **Section Title:** Getting Started with Git **Topic:** Understanding the Git directory structure: Working directory, staging area, and repository. **Introduction** In the previous topics, we covered the basics of Git and understanding how to initialize a local Git repository, clone an existing repository, and manage changes with basic Git commands. In this topic, we will dive deeper into the Git directory structure, exploring the three key components: the working directory, the staging area, and the repository. Understanding these components is essential to mastering Git and effectively managing your codebase. **The Git Directory Structure** When you initialize a new Git repository using `git init`, a hidden directory named `.git` is created within your project directory. The `.git` directory contains all the metadata needed to manage the repository, including the commit history, branches, and tags. The Git directory structure consists of three main areas: ### 1. Working Directory The working directory, also known as the working tree, is the directory where you make changes to your files. It's the directory where you create, edit, and delete files. The working directory is outside of the `.git` directory. Think of the working directory as your "scratch space" where you work on your code before committing it to the repository. **Example** Suppose you have a project directory with the following structure: ```bash myproject/ file1.txt file2.txt .git/ ``` In this example, the `myproject` directory is the working directory. ### 2. Staging Area The staging area, also known as the index, is a temporary area where changes are stored before they are committed to the repository. When you run `git add <file>`, the changes are staged in the staging area. The staging area is within the `.git` directory. **Example** Using the same example as above, suppose you make changes to `file1.txt` and run `git add file1.txt`. The changes are now staged in the staging area. ```bash myproject/ file1.txt (changed) file2.txt .git/ index # staging area ``` ### 3. Repository The repository is where all the commits, branches, and tags are stored. When you run `git commit`, the staged changes are saved to the repository. The repository is also within the `.git` directory. **Example** Using the same example as above, suppose you run `git commit -m "Updated file1.txt"`. The changes are now saved to the repository. ```bash myproject/ file1.txt file2.txt .git/ index # staging area objects/ # repository ``` **Understanding the Workflow** To illustrate how these three areas work together, let's go through a simple workflow: 1. Make changes to your files in the working directory. 2. Run `git add` to stage the changes in the staging area. 3. Run `git commit` to save the staged changes to the repository. **Conclusion** Understanding the Git directory structure is crucial to mastering Git. The working directory is where you make changes to your files, the staging area is where changes are stored before being committed, and the repository is where all the commits, branches, and tags are stored. In the next topic, we will explore how to view commit history using `git log`.
