Linux 目录变化监听 - python代码实现

在python中 文件监控主要有两个库，

一个是pyinotify （ https://github.com/seb-m/pyinotify/wiki ），pyinotify依赖于Linux平台的inotify。

一个是watchdog（http://pythonhosted.org/watchdog/）。对不同平台的的事件都进行了封装。

1、watchdog实现

　　

from watchdog.observers import Observer
from watchdog.events import *
import time

class FileEventHandler(FileSystemEventHandler):
    def __init__(self):
        FileSystemEventHandler.__init__(self)

    def on_moved(self, event):
        if event.is_directory:
            print("directory moved from {0} to {1}".format(event.src_path,event.dest_path))
        else:
            print("file moved from {0} to {1}".format(event.src_path,event.dest_path))

    def on_created(self, event):
        if event.is_directory:
            print("directory created:{0}".format(event.src_path))
        else:
            print("file created:{0}".format(event.src_path))

    def on_deleted(self, event):
        if event.is_directory:
            print("directory deleted:{0}".format(event.src_path))
        else:
            print("file deleted:{0}".format(event.src_path))

    def on_modified(self, event):
        if event.is_directory:
            print("directory modified:{0}".format(event.src_path))
        else:
            print("file modified:{0}".format(event.src_path))

if __name__ == "__main__":
    observer = Observer()
    event_handler = FileEventHandler()
    observer.schedule(event_handler,"d:/dcm",True)
    observer.start()
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        observer.stop()
    observer.join()

2、pyinotify
