About:
FseventsTools provides command-line utilities for monitoring file system changes on macOS using the native FSEvents API. It offers a low-overhead alternative to polling-based tools like fswatch or inotifywait. The suite includes fseventsd for daemonizing event streams and fsevents_watch for immediate directory monitoring.
Key Features:
  • Native macOS FSEvents API integration
  • Low CPU overhead compared to polling
  • Daemon mode for background monitoring
  • Script-friendly output formatting
Use Cases:
  • Triggering build scripts on file changes
  • Monitoring log files for real-time analysis
  • Automating deployment workflows on file updates
Alternatives:
  • fswatch – Cross-platform with multiple backends; FseventsTools is macOS-specific but more efficient
  • inotify-tools – Linux-only; FseventsTools provides equivalent functionality for macOS
