How files move between three areas in Git - Try It Yourself

How files move between three areas in Git

📖 Scenario: You are working on a simple project using Git. You want to understand how files move between the three main areas in Git: the working directory, the staging area (index), and the repository (commit history).

🎯 Goal: Learn how to create a file, add it to the staging area, and commit it to the Git repository. This will help you understand the flow of files in Git.

📋 What You'll Learn

Create a new file called example.txt with some text

Add the file example.txt to the Git staging area using git add

Commit the staged file with the message Initial commit of example.txt

Show the commit log to verify the commit

💡 Why This Matters

🌍 Real World

Understanding how files move between the working directory, staging area, and repository is essential for managing changes in any software project using Git.

💼 Career

This knowledge is fundamental for developers, DevOps engineers, and anyone working with version control systems to collaborate and track code changes effectively.

1

Create a new file in the working directory

Create a file called example.txt in your working directory with the content Hello, Git! using the command echo "Hello, Git!" > example.txt.

Git

# Create the file example.txt with the text Hello, Git!
# Your code here

Need a hint?

Use the echo command to write text into a file.

2

Add the file to the Git staging area

Use the command git add example.txt to add the file example.txt to the Git staging area.

Git

echo "Hello, Git!" > example.txt
# Add example.txt to the staging area
# Your code here

Need a hint?

The git add command moves files from the working directory to the staging area.

3

Commit the staged file to the repository

Commit the staged file using the command git commit -m "Initial commit of example.txt" to save it in the Git repository.

Git

echo "Hello, Git!" > example.txt
git add example.txt
# Commit the staged file with the message
# Your code here

Need a hint?

The git commit command saves the staged changes to the repository with a message.

4

Show the commit log

Use the command git log --oneline to display the commit history and verify your commit.

Git

echo "Hello, Git!" > example.txt
git add example.txt
git commit -m "Initial commit of example.txt"
# Show the commit log
# Your code here

Need a hint?

The git log --oneline command shows a short summary of commits.
