Look for file changes and kick off actions with Watchman

On Guard

Conclusion

Watchman is a flexible tool under active development. Even if its usage seems unfriendly, learning some basic functionality can help you accomplish complex tasks with your own scripts. Here, I looked at two use cases: triggering rsync and a real-time virus scanner. Instead of triggering an action, you could also simply query Watchman for changes that happen inside a directory during a given period. The uses for Watchman are numerous: No doubt a number of applications have occurred to you already.
