git diff-files [options] [files...]

git diff-files compares the working tree with the index (staging area), operating as a low-level plumbing command that shows unstaged changes. It is used internally by git diff when invoked without arguments and provides the foundation for higher-level diff operations.
This command is part of Git's plumbing layer, designed for scripting and automation rather than daily interactive use. It can produce various output formats including raw diff data, patch format, or simple file lists, making it suitable for integration into build tools, pre-commit hooks, or custom Git workflows.

--raw

Raw diff format.

Exit with 1 if differences.
