git diff HEAD HEAD^
Displays the differences between the two most recent commits.
This command utilizes git diff to create a comparison or 'diff' between the latest commit, represented by HEAD, and its immediate predecessor, denoted by HEAD^.
The diff illustrates changes between the contents of these two snapshots, showing which lines were added or removed.
Variants of this command could include flags such as --stat to show the differences in a statistical format, or --color-words to highlight changed words instead of the whole line.
