Tips

  • Safety first, if your Ubuntu system is mission-critical, wait for Fub to mature before full cleanups.
  • Preview the cleanup by running fub clean --dry-run and reviewing the generated list.
  • Use fub clean --whitelist to manage protected caches.
  • Use fub touchid to approve sudo with Touch ID instead of typing your password.
