git commit -a to skip staging - Mini Project: Build & Apply

Using git commit -a to Skip Staging

📖 Scenario: You are working on a small project and have modified some files. Normally, you would add these files to the staging area before committing. But you want to save time by committing all changes directly without manually staging them.

🎯 Goal: Learn how to use the git commit -a command to commit all modified and deleted files directly, skipping the staging step.

📋 What You'll Learn

Create a new file and commit it using normal git commands

Modify an existing file

Use git commit -a to commit the changes without staging

Verify the commit includes the changes

💡 Why This Matters

🌍 Real World

Developers often make quick changes and want to commit them without the extra step of staging each file. Using git commit -a saves time in these cases.

💼 Career

Knowing how to efficiently commit changes is essential for software developers and DevOps engineers to maintain clean and fast workflows.

1

Create a new file and commit it normally

Create a new file called example.txt with the content Hello World. Then use git add example.txt and git commit -m "Add example.txt" to commit it.

Git

# Create example.txt with content 'Hello World'
# Then run git add and git commit commands
# Your code here

Need a hint?

Use echo "Hello World" > example.txt to create the file. Then add and commit it normally.

2

Modify the existing file

Modify the file example.txt by adding the line This is a change at the end. Use echo with append operator >> to do this.

Git

echo "Hello World" > example.txt

# Add the new file to staging
!git add example.txt

# Commit the staged file
!git commit -m "Add example.txt"

# Append 'This is a change' to example.txt
# Your code here

Need a hint?

Use echo "This is a change" >> example.txt to add the line at the end.

3

Commit changes using git commit -a

Use the command git commit -a -m "Update example.txt with change" to commit the modified example.txt file without using git add.

Git

echo "Hello World" > example.txt

# Add the new file to staging
!git add example.txt

# Commit the staged file
!git commit -m "Add example.txt"

echo "This is a change" >> example.txt

# Commit the change using git commit -a
# Your code here

Need a hint?

Use git commit -a -m "Update example.txt with change" to commit all modified files directly.

4

Verify the commit includes the changes

Use git log -1 --pretty=%B to print the last commit message and verify it is Update example.txt with change.

Git

echo "Hello World" > example.txt

# Add the new file to staging
!git add example.txt

# Commit the staged file
!git commit -m "Add example.txt"

echo "This is a change" >> example.txt

!git commit -a -m "Update example.txt with change"

# Print the last commit message
# Your code here

Need a hint?

Use git log -1 --pretty=%B to see the last commit message.
