Summary: Blame options
git blame displays the latest modifications to file lines with commit and author information. You can inspect the commit ID with git show to understand the context of the change. In large files, use the -L option to focus on a specific line range.
git blame -L 15,30 app.js
git show a12bc34Blame identifies the commit that last modified a line; this is not always the commit that first introduced it.
