![]() There are three options to workaround this problem: Anything after the loop will not be executed because monitoring is expected to happen continuously. The call to loop() is blocking the current process in this example. Observe the output in the terminal as commands are executed in the monitored directory. Use different shell commands to manipulate files within the watched directory to fire other events: touch test_file.txt Observe that not only files are opened but also directories are opened too.Ĭhange the current working directory to notification_dir with cd: cd notification_dir abspath ( "notification_dir" ) watch_manager. ![]() Notifier ( watch_manager, EventProcessor ()) watch_this = os. WatchManager () event_notifier = pyinotify. _methods : process_generator ( EventProcessor, method ) watch_manager = pyinotify. _name_, _method_name ) for method in EventProcessor. format ( method ) setattr ( cls, _method_name. ProcessEvent ): _methods = def process_generator ( cls, method ): def _method_name ( self, event ): print ( "Method name: process_ ". Import os import pyinotify class EventProcessor ( pyinotify. This guide will breakdown the code into smaller bits. The EventProcessor class contain methods that print out the monitored file or directory will along with the corresponding inotify event. Similar to IN_MOVED_FROM except for outgoing file/directoryįilesystem of watched file/directory unmounted from systemīelow is the full script used in this guide.

For example, IN_CREATE in pyinotify though the EventProcessor will be process_IN_CREATE. Similar to events in inotify, the Python implementation will be through an EventProcessor object with method names containing “process_” that is appended before the event name. Set Up Filesystem Tracking Create an Event Processor Install pyinotify within the virtual environment: pip install pyinotify This guide will use Miniconda, but virtualenv can also be used.Ĭreate a virtual environment in Anaconda: conda create -n myenv python=3Īctivate the new environment: source activate myenv Installing pyinotify within a virtual environment is highly recommended. Restart your shell session for the changes to your PATH to take effect.Ĭheck your Python version: python -version Review the terms and conditions and select “yes” for each prompt. You will be prompted several times during the installation process. Install Python 3ĭownload and install Miniconda: curl -OL This guide will demonstrate how to use a Python script to monitor a directory then explore practical uses by incorporating async modules or running additional threads. It does not store any personal data.File system monitoring through inotify can be interfaced through Python using pyinotify.
