Summary - Diff

Combine diff options to inspect the change flow.

Compare changes correctly

To inspect changes in Git, you need to know which areas are being compared. git diff shows the difference between the working tree and the staging area. git diff --cached compares staged changes with the current commit, HEAD.

git diff
git diff --cached

These two commands let you review both unstaged changes and changes prepared for a commit.

Exercise Inspect both groups of changes

First inspect unstaged differences in the working tree with git diff, then inspect staged differences with git diff --cached. Write the two commands on separate lines.
