怎么监控文件被哪些进程修改了 golang-Go服务器开发

要监控文件被哪些进程修改了，您可以使用Golang中的os包和fsnotify包来实现。下面是一个简单的示例代码：

package main
import (
	"fmt"
	"os"
	"path/filepath"
	"github.com/fsnotify/fsnotify"
)
func main() {
	filePath := "/path/to/your/file.txt"
	watcher, err := fsnotify.NewWatcher()
	if err != nil {
		fmt.Println("Failed to create watcher:", err)
		return
	}
	defer watcher.Close()
	err = watcher.Add(filepath.Dir(filePath))
	if err != nil {
		fmt.Println("Failed to add directory to the watcher:", err)
		return
	}
	done := make(chan bool)
	go func() {
		for {
			select {
			case event, ok := <-watcher.Events:
				if !ok {
					return
				}
				if event.Name == filePath && (event.Op&fsnotify.Write == fsnotify.Write || event.Op&fsnotify.Chmod == fsnotify.Chmod) {
					processes, err := processesWithFileOpen(filePath)
					if err != nil {
						fmt.Println("Failed to get processes:", err)
					} else {
						fmt.Printf("File %s modified by processes: %v\n", filePath, processes)
					}
				}
			case err, ok := <-watcher.Errors:
				if !ok {
					return
				}
				fmt.Println("Error occurred:", err)
			}
		}
	}()
	fmt.Println("Monitoring changes to file:", filePath)
	<-done
}
// 获取打开指定文件的进程列表
func processesWithFileOpen(filePath string) ([]string, error) {
	processes := []string{}
	fileInfo, err := os.Stat(filePath)
	if err != nil {
	  return nil, err
	}
  
	fileInode := fileInfo.Sys().(*syscall.Stat_t).Ino
	processesData, err := ioutil.ReadFile("/proc/net/unix")
	if err != nil {
	  return nil, err
	}
	lines := strings.Split(string(processesData), "\n")
	for _, line := range lines {
	  fields := strings.Fields(line)
	  if len(fields) >= 9 && fields[8] == filePath {
		pid, _ := strconv.Atoi(fields[6])
  
		cmdlineBytes, _ := ioutil.ReadFile(fmt.Sprintf("/proc/%d/cmdline", pid))
		cmdline := string(bytes.Replace(cmdlineBytes, []byte{0}, []byte{' '}, -1))
  
		processes = append(processes, fmt.Sprintf("%d: %s", pid, cmdline))
	  }
	}
	return processes, nil
}
