How Git stores objects - Try It Yourself

How Git Stores Objects

📖 Scenario: You are learning how Git saves your files and changes internally. Git stores data as objects in a special folder. Understanding this helps you see how Git tracks your work.

🎯 Goal: You will create a simple Git repository, add a file, commit it, and then explore how Git stores the file as an object.

📋 What You'll Learn

Create a new Git repository

Add a file with specific content

Commit the file to Git

Use Git commands to find and show the stored object

💡 Why This Matters

🌍 Real World

Understanding Git objects helps you know how your code changes are saved safely and efficiently.

💼 Career

Developers and DevOps engineers use Git daily; knowing its internals helps in debugging and advanced version control.

1

Create a new Git repository

Run the command git init myrepo to create a new Git repository folder called myrepo.

Git

# Run the command to create a new Git repository folder called myrepo
# Your code here

Need a hint?

Use git init followed by the folder name myrepo.

2

Add a file with content

Inside the myrepo folder, create a file named hello.txt with the exact content Hello Git!.

Git

git init myrepo
# Create a file hello.txt inside myrepo with content 'Hello Git!'
# Your code here

Need a hint?

Use echo "Hello Git!" > hello.txt inside the myrepo folder.

3

Commit the file to Git

Run git add hello.txt and then git commit -m "Add hello.txt" inside the myrepo folder to save the file in Git.

Git

git init myrepo
cd myrepo
echo "Hello Git!" > hello.txt
# Add hello.txt to Git and commit with message 'Add hello.txt'
# Your code here

Need a hint?

Use git add hello.txt to stage the file, then git commit -m "Add hello.txt" to commit.

4

Find and show the Git object

Run git hash-object hello.txt to get the object hash, then run git cat-file -p <hash> replacing <hash> with the hash to see the stored content.

Git

git init myrepo
cd myrepo
echo "Hello Git!" > hello.txt
git add hello.txt
git commit -m "Add hello.txt"
# Get the object hash of hello.txt and display its content
# Your code here

Need a hint?

Use git hash-object hello.txt to get the hash, save it in a variable, then use git cat-file -p with that hash.
