Explanation

Filters and formats commit history: --oneline for compact view, -p for patches, --stat for file stats, and --grep/--author for searching. --follow tracks a file through renames, and --graph visualizes branch structure. --since/--until and --pretty=format enable date-range and custom-format output.
