Git Blame in Git & GitHub

git blame shows who wrote each line of code and when. It answers "Who added this line?" and "When was it added?". Useful for understanding code history and reaching out to the original author.

On GitHub, you can click on a line to see the commit and author. In the terminal, `git blame file.js` shows line-by-line authorship.

Arjun finds a strange line of code and wonders who added it. He uses `git blame` to see "Priya added this on 2024-01-15 in commit abc123 for fixing issue #42".

Git Blame — Syntax

git blame <file>                # Show authorship of each line
git blame -L 10,20 <file>       # Blame specific lines 10-20
