python3.6 Linux下使用pyinotify監聽文件目錄

Demo

import pyinotify
import sys
import os

WATCH_PATH = '/home/newdata'  # 監控目錄

if not WATCH_PATH:
    print("The WATCH_PATH setting MUST be set.")
    sys.exit()
else:
    if os.path.exists(WATCH_PATH):
        print('Found watch path: path=%s.' % (WATCH_PATH))
    else:
        print('The watch path NOT exists, watching stop now: path=%s.' % (WATCH_PATH))
        sys.exit()

        file_path = os.path.join(event.path, event.name)
        print('文件完成寫入',file_path)

if __name__ == "__main__":
    auto_compile(WATCH_PATH)
    print('monitor close')
