inotify

inotify — it is a Go library for monitoring changes in the Linux file system using the low-level inotify interface. It is inspired by fsnotify, but provides more direct and flexible access to file system events, including:

• recursive directory tracking (/path/...);
• Flag support inotify, including IN_CREATE, IN_DELETE, IN_MODIFY, IN_MOVE_SELF, IN_MOVE_TO, IN_MOVE_FROM;
• Automatic addition of new subdirectories when they are created.

Usage example

package main

import (
    "log"
)

func main() {
    watcher, err := inotify.NewWatcher()
    if err != nil {
        log.Fatal(err)
    }
    defer watcher.Close()

    err = watcher.Add("/path/to/dir/...")
    if err != nil {
        log.Fatal(err)
    }

    for {
        select {
        case event := <-watcher.Events:
            log.Printf("Event: %s %x\n", event.Name, event.Op)
        case err := <-watcher.Errors:
            log.Printf("Error: %v\n", err)
        }
    }
}
