常用示例
Compare index to commit
git diff-index HEAD
Compare working tree to commit
git diff-index [commit]
Check for differences
git diff-index --quiet HEAD
Raw output format
git diff-index --raw HEAD
说明
git diff-index compares a tree object to the working tree or index, operating as a low-level plumbing command used internally by git diff for commit comparisons. It accepts a tree-ish (commit, branch, tag, or tree object) and compares it against either the index (with --cached) or the working tree. The tool is particularly useful in automation scenarios that need to detect whether files have changed since a specific commit, such as CI/CD pipelines checking for uncommitted modifications or scripts validating clean working directories. Its --quiet flag enables simple boolean checks for changes without processing full diff output.
