Answer 1

You can use Pyfanotyfi or butter.

I think you'll find this link very usefull: Linux file system events with C, Python and Ruby

There you will find an example about doing exactly what you want(using pyinotify) this is the code:

import pyinotify

DIR_TO_WATCH="/tmp/notify-dir"
FILE_TO_WATCH="/tmp/notify-dir/notify-file.txt"

wm = pyinotify.WatchManager()

dir_events = pyinotify.IN_DELETE | pyinotify.IN_CREATE
file_events = pyinotify.IN_OPEN | pyinotify.IN_CLOSE_WRITE | pyinotify.IN_CLOSE_NOWRITE

class EventHandler(pyinotify.ProcessEvent):
    def process_IN_DELETE(self, event):
        print("File %s was deleted" % event.pathname) #python 3 style print function
    def process_IN_CREATE(self, event):
        print("File %s was created" % event.pathname)
    def process_IN_OPEN(self, event):
        print("File %s was opened" % event.pathname)
    def process_IN_CLOSE_WRITE(self, event):
        print("File %s was closed after writing" % event.pathname)
    def process_IN_CLOSE_NOWRITE(self, event):
        print("File %s was closed after reading" % event.pathname)

event_handler = EventHandler()
notifier = pyinotify.Notifier(wm, event_handler)

wm.add_watch(DIR_TO_WATCH, dir_events)
wm.add_watch(FILE_TO_WATCH, file_events)

notifier.loop()
