Is there a library?

Question

go

I need to watch files in a certain directory. If I give something changed / added / removed, I need to run the function. I think that such libraries exist for sure. If not, is there a library in order to get the time of the last update (and I will screw the function call myself already). I just don't want to ride a bike (although I work for an hour or two)

or read hashes from files and save them to a file
