💡 Why This Matters

🌍 Real World

In real projects, sometimes you make changes you don't want to keep. Using <code>git restore</code> helps you quickly undo those changes without affecting your commits.

💼 Career

Knowing how to discard unwanted changes is essential for developers and DevOps engineers to maintain clean code and avoid mistakes in version control.

1

Create a file with initial content

Create a file called example.txt with the exact content Hello, Git! and add it to the Git repository with git add example.txt and commit with the message Initial commit.

Git

# Create example.txt with content and commit
# Your code here

Need a hint?

Use echo to create the file, then git add and git commit to save it.

2

Modify the file to simulate changes

Modify the file example.txt by adding the line This is a change. to simulate uncommitted changes.

Git

echo "Hello, Git!" > example.txt
git add example.txt
git commit -m "Initial commit"
# Add a new line 'This is a change.' to example.txt
# Your code here

Need a hint?

Use echo with >> to append the new line to the file.

3

Discard the changes using git restore

Use the command git restore example.txt to discard the uncommitted changes in example.txt and restore it to the last committed state.

Git

echo "Hello, Git!" > example.txt
git add example.txt
git commit -m "Initial commit"
echo "This is a change." >> example.txt
# Use git restore to discard changes in example.txt
# Your code here

Need a hint?

Use git restore followed by the filename to discard changes.

4

Verify the file content is restored

Use cat example.txt to display the content of example.txt and verify it only contains Hello, Git! without the discarded line.

Git

echo "Hello, Git!" > example.txt
git add example.txt
git commit -m "Initial commit"
echo "This is a change." >> example.txt
git restore example.txt
# Display the content of example.txt
# Your code here

Need a hint?

Use cat example.txt to see the file content.
