TIL: Git Commands Before Reading Code

I started contributing to the Code for Philly PAX project and inspected the codebase by running the git commands Ally Piechowskiuses to identify code churn hotspots, bus factor, bug clusters, and crisis patterns.

What Changes the Most:

git log --format=format: --name-only --since="1 year ago" | sort | uniq -c | sort -nr | head -20

Who Built This:

git shortlog -sn --no-merges

Where Do Bugs Cluster:

git log -i -E --grep="fix|bug|broken" --name-only --format='' | sort | uniq -c | sort -nr | head -20

Is This Project Accelerating or Dying:

git log --format='%ad' --date=format:'%Y-%m' | sort | uniq -c

How Often Is the Team Firefighting:

git log --oneline --since="1 year ago" | grep -iE 'revert|hotfix|emergency|rollback'
