💡 Why This Matters

🌍 Real World

Developers use <code>git fsck</code> to verify their Git repositories are not corrupted before pushing or deploying code.

💼 Career

Knowing how to check repository health is important for software engineers and DevOps professionals to maintain code integrity.

1

Initialize a Git repository

Open your terminal and create a new directory called myproject. Then, initialize a Git repository inside it by running git init.

Git

# Create a directory named myproject and initialize a Git repository inside it
# Your code here

Need a hint?

Use mkdir myproject to create the folder, then cd myproject to enter it, and finally git init to start the repository.

2

Create a file and commit it

Inside the myproject directory, create a file named README.md with the text "My project". Then add and commit this file to the Git repository using git add README.md and git commit -m "Initial commit".

Git

mkdir myproject
cd myproject
git init
# Create README.md with text "My project" and commit it
# Your code here

Need a hint?

Use echo "My project" > README.md to create the file with content, then add and commit it.

3

Run git fsck to check repository integrity

Run the command git fsck inside the myproject directory to check the repository for any broken or missing objects.

Git

mkdir myproject
cd myproject
git init
echo "My project" > README.md
git add README.md
git commit -m "Initial commit"
# Run git fsck to check repository integrity
# Your code here

Need a hint?

Simply type git fsck and press Enter to check the repository.

4

Interpret the git fsck output

Observe the output of git fsck. If the repository is healthy, it should show no errors. Print the message "Repository is healthy" if no errors are found.

Git

mkdir myproject
cd myproject
git init
echo "My project" > README.md
git add README.md
git commit -m "Initial commit"
git fsck
# Print "Repository is healthy" if no errors
# Your code here

Need a hint?

Check the exit status of git fsck with $?. If it is 0, print the message.
