In order to ensure files are present on your computer and performing as they should, it may be important for you to set up a framework for keeping track of their whereabouts and consistency over time. Changes to file metadata are monitored as well including file ownership, filegroup, file flags, and file access control list. Events include changes to files, changes to the list of files within a directory, and changes to file meta-data such as access control lists. Watchdog is a Python library that provides API and shell utilities to monitor file changes using Python. Users can also provide multiple event handlers and can execute shell scripts when an event is triggered. Handlers can be registered in response to events on a single file, or on all events on a directory. Watchdog operates by registering file system event handlers that fire whenever the corresponding event occurs. Watchdog could be used for a number of common tasks, such as watching for changes in file systems, watching for file systems events, and observing file systems directory. The Watchdog is an open-source application that allows you to monitor file changes using Python. We’ll take a look at how it works, what it can be used for, and provide some insight into how you can use it to monitor file system events in your own applications. We’re going to use Watchdog which is a Python library that offers APIs and shell utilities to monitor file changes using Python. In this tutorial, we’ll look at how we can monitor file changes using Python.
