用pyinotify监控文件系统示例详解编程语言

pyinotify其实就是通过调用系统的inotify来实现通知的。

1. 安装

git clone https://github.com/seb-m/pyinotify.git 
cd pyinotify/ 
python setup.py install

2. 简单使用

import os 
from pyinotify import WatchManager, Notifier, ProcessEvent, IN_DELETE, IN_CREATE, IN_MODIFY 
 
class EventHandler(ProcessEvent): 
    def process_IN_CREATE(self, event): 
        print "Create file:%s." %os.path.join(event.path,event.name) 
 
        os.system('cp -rf %s /tmp/bak/'%(os.path.join(event.path,event.name))) 
    def process_IN_DELETE(self, event): 
        print "Delete file:%s." %os.path.join(event.path,event.name) 
 
    def process_IN_MODIFY(self, event): 
        print "Modify file:%s." %os.path.join(event.path,event.name) 
 
def FsMonitor(path='.'): 
    wm = WatchManager() 
    mask = IN_DELETE | IN_CREATE | IN_MODIFY 
    notifier = Notifier(wm, EventHandler()) 
    wm.add_watch(path, mask, auto_add= True, rec=True) 
    print "now starting monitor %s." %path 
 
    while True: 
        try: 
            notifier.process_events() 
            if notifier.check_events(): 
                print "check event true." 
                notifier.read_events() 
        except KeyboardInterrupt: 
            print "keyboard Interrupt." 
            notifier.stop() 
            break 
 
if __name__ == "__main__": 
    FsMonitor("/root/work/")
