Git recovery skills are essential for developers, DevOps engineers, and anyone working with version control to maintain code integrity and fix errors efficiently.

1

Create a Git repository and add a file

Initialize a Git repository with git init. Create a file named notes.txt with the content Hello Git. Add the file to Git with git add notes.txt and commit it with the message Initial commit using git commit -m "Initial commit".

Git

# Initialize Git repo and add notes.txt
# Your code here

Need a hint?

Use git init to start a repo. Use echo to create the file. Then add and commit.

2

Simulate a mistake by deleting the file

Delete the file notes.txt using rm notes.txt. Check the Git status with git status to see the file is deleted but not committed yet.

Git

git init

echo "Hello Git" > notes.txt

git add notes.txt

git commit -m "Initial commit"

# Delete notes.txt and check git status
# Your code here

Need a hint?

Use rm to delete the file. Then run git status to see the change.

3

Recover the deleted file using Git

Use git checkout -- notes.txt to restore the deleted file from the last commit. This recovers your file without losing any work.

Git

git init

echo "Hello Git" > notes.txt

git add notes.txt

git commit -m "Initial commit"

rm notes.txt

git status

# Recover notes.txt using git checkout
# Your code here

Need a hint?

Use git checkout -- filename to restore a deleted file from the last commit.

4

Display the recovered file content

Use cat notes.txt to display the content of the recovered file and confirm it says Hello Git.

Git

git init

echo "Hello Git" > notes.txt

git add notes.txt

git commit -m "Initial commit"

rm notes.txt

git status

git checkout -- notes.txt

# Show the content of notes.txt
# Your code here

Need a hint?

Use cat filename to see the file content in the terminal.
