git guilt [options]git guilt [options] since [until]

git guilt shows the delta in blame between two commits, calculating which authors gained or lost lines of code between the specified revisions. The output shows net line changes per author as a bar of pluses or minuses, with positive lengths indicating a net gain in attributed lines and negative indicating a net loss. Run with no arguments, it shows the blame count for currently unstaged modified files instead of comparing two revisions.Part of the git-extras suite, this tool reveals who is actively modifying which areas of the codebase, useful for understanding recent code ownership changes.
