详解如何使用Go语言进行文件监控和通知

go get github.com/fsnotify/fsnotify

package main

import (
	"fmt"
	"log"
	"path/filepath"

	"github.com/fsnotify/fsnotify"
)

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

	done := make(chan bool)

	go func() {
		for {
			select {
			case event, ok := <-watcher.Events:
				if !ok {
					return
				}
				fmt.Println("event:", event)
				if event.Op&fsnotify.Write == fsnotify.Write {
					fmt.Println("modified file:", event.Name)
				}
			case err, ok := <-watcher.Errors:
				if !ok {
					return
				}
				fmt.Println("error:", err)
			}
		}
	}()

	err = watcher.Add("/path/to/watch")
	if err != nil {
		log.Fatal(err)
	}
	<-done
}

import (
	"os/exec"
	"fmt"
)

func sendNotification(title, message string) {
	cmd := exec.Command("notify-send", title, message)
	err := cmd.Run()
	if err != nil {
		fmt.Println("Error sending notification:", err)
	}
}

// 在文件被修改时调用这个函数
func handleModifiedFile(filename string) {
	sendNotification("File Modified", filename)
}
