git diff-index

Compare the working directory with a commit or tree object. More information: https://git-scm.com/docs/git-diff-index.

• Compare the working directory with a specific commit:

git diff-index {{commit}}

• Compare a specific file or directory in working directory with a commit:

git diff-index {{commit}} {{path/to/file_or_directory}}

• Compare the working directory with the index (staging area) to check for staged changes:

git diff-index --cached {{commit}}

• Suppress output and return an exit status to check for differences:

git diff-index --quiet {{commit}}
