Git Practice Lesson 9 of 9

Fix the bug: forgot to switch branches

Every lesson so far asked you to type a script from scratch. Real work is more often the opposite: someone else's script is already there, and it's broken. This one doesn't throw an error or print anything scary - it runs clean, top to bottom, and looks like it worked. That's what makes it worth knowing: a wrong branch doesn't crash, it just quietly commits your work in the wrong place.

The script below is supposed to create a branch called feature and commit feature.txt there, keeping main untouched. Run it, then check where the commit actually landed - git branch --show-current or git log --oneline will tell you the truth. git branch feature only creates the branch. It doesn't move you onto it - you're still standing on whatever branch you were already on when the next commands run.

Your task: fix the script so the commit for feature.txt lands on feature, not main. When you're done, main should still have only its original commit.

You'll practice:

Noticing that git branch <name> creates a branch without switching to it
Reaching for git checkout -b <name> when you want both in one step

# This script is broken - it's supposed to commit feature.txt on a new branch called feature, but the commit lands on main instead. Fix it.
git branch feature
git add feature.txt
git commit -m "Add feature.txt"
