watchdog monitoring file for changes
Instead of LoggingEventHandler
define your handler:
#!/usr/bin/python
import time
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
class MyHandler(FileSystemEventHandler):
def on_modified(self, event):
print(f'event type: {event.event_type} path : {event.src_path}')
if __name__ == "__main__":
event_handler = MyHandler()
observer = Observer()
observer.schedule(event_handler, path='/data/', recursive=False)
observer.start()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
observer.stop()
observer.join()
on_modified
is called when a file or directory is modified.
Here's a snippet to prevent it running twice as others have commented in @alecxe answer:
from datetime import datetime, timedelta
class MyHandler(FileSystemEventHandler):
def __init__(self):
self.last_modified = datetime.now()
def on_modified(self, event):
if datetime.now() - self.last_modified < timedelta(seconds=1):
return
else:
self.last_modified = datetime.now()
print(f'Event type: {event.event_type} path : {event.src_path}')
print(event.is_directory) # This attribute is also available
