This exercise comes with a starter repo that you will need to clone down to your machine. We will be working with two bands: Queen and Fleetwood Mac and their various lineups over the years.

Part 1: Setup

Please run the following commands from your terminal. Make sure you are not inside of a Git repo.

git clone <https://github.com/Colt/git-diff-exercise>

• Change into the newly created folder called git-diff-exercise. You will be on a branch called current by default.
• Run git switch 1970s
• You should now have two branches that you can move between: current and 1970s Each branch contains two files: queen.txt and fleetwoodmac.txt

Part 2: The Diffs

1. Compare the difference between the 1970s branch and the current branch across all files
2. Compare the difference between the 1970s branch and the current branch but only for the queen.txt file
3. Switch over to the current branch if you are not currently on it. Run a diff to compare the current HEAD to the previous commit (you could use the commit hash or reference HEAD's parent commit)
4. While on the current branch, change the queen.txt file by replacing Adam Lambert with your own name. Save the change. Add queen.txt to the staging area. DO NOT COMMIT YET!
5. Edit the fleetwoodmac.txt file, changing the lead singer from Stevie Nicks to Stevie Chicks (one of my chickens). Save the file, but do not stage it.
6. Run a diff that would reveal the unstaged changes in the working directory (you should see only the change to fleetwoodmac.txt printed out)
7. Run a diff that would reveal only the staged changes (you should only see the change to queen.txt printed out)
8. Run a diff that prints all changes (staged and unstaged) since the prior commit (you should see both changes printed out)
