Git - Squashing Commits - Solution

1. In a git repository, create a new file with the content "Mario" and commit the change

git add new_file
echo "Mario" -> new_file
git commit -a -m "New file"

2. Make change to the content of the file you just created so the content is "Mario & Luigi" and create another commit

echo "Mario & Luigi" > new_file
git commit -a -m "Added Luigi"

3. Verify you have two separate commits - git log

4. Squash the two commits you've created into one commit

git rebase -i HEAD~2

You should see something similar to:

pick 5412076 New file
pick 4016808 Added Luigi

Change pick to squash

pick 5412076 New file
squash 4016808 Added Luigi

Save it and provide a commit message for the squashed commit

After you complete the exercise

Answer the following:

• What is the reason for squashing commits? - history becomes cleaner and it's easier to track changes without commit like "removed a character" for example.
• Is it possible to squash more than 2 commits? - yes
