用python监视文件变化

最近在做一个项目，要监视一个目录下文件的变化，不多说，先看代码：

第一种方式：

#!/usr/bin/env python#coding=utf-8 import osimport gtkimport gobjectfrom  pyinotify import  WatchManager, Notifier, ProcessEvent, ThreadedNotifier, IN_DELETE, IN_CREATE,IN_MOVED_TO,IN_MOVED_FROM class hechao(ProcessEvent):    def process_IN_CREATE(self, event):        print   "创建文件: %s "  %   os.path.join(event.path, event.name)     def process_IN_DELETE(self, event):        print   "删除文件: %s "  %   os.path.join(event.path, event.name)     def process_IN_MOVED_TO(self, event):        print   "移来文件: %s "  %   os.path.join(event.path, event.name)     def process_IN_MOVED_FROM(self, event):        print   "移走文件: %s "  %   os.path.join(event.path, event.name) path = "/home/hechao/.gnomenu/favorites"gobject.threads_init()wm = WatchManager() mask = IN_DELETE|IN_CREATE|IN_MOVED_TO|IN_MOVED_FROMnotifier = ThreadedNotifier(wm, hechao())wm.add_watch(path, mask,rec=True)notifier.start() def __quit(widget):notifier.stop()gtk.main_quit() if __name__ == "__main__":    win = gtk.Window()    win.connect("destroy",__quit)    win.show()    gtk.main()

第二种方式：

import giodef directory_changed(monitor, file1, file2, evt_type):    print evt_type    if evt_type == gio.FILE_MONITOR_EVENT_CREATED or evt_type == gio.FILE_MONITOR_EVENT_DELETED:    print "测试成功！"    print "变化：",evt_typeprint type(evt_type)  gfile = gio.File(".")monitor = gfile.monitor_directory(gio.FILE_MONITOR_NONE, None)monitor.connect("changed", directory_changed)  import glibml = glib.MainLoop()ml.run()

再加一个定时器就OK了。
