print "modify directory: %s" % event.src_path
if __name__ == "__main__":
path = sys.argv[1] if len(sys.argv) > 1 else './test/'
event_handler = EventHandler()
observer = Observer()
observer.schedule(event_handler, path, recursive=True)
observer.start()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
observer.stop()
observer.join()

其中EventHandler继承自FileSystemEventHandler，其中可以针对不同的文件操作类型编写不同的处理逻辑。
