inotify-tools is a set of command-line utilities that provides a simple interface to the inotify kernel subsystem. It allows users to monitor and react to changes in files and directories in real-time. The package includes two main utilities: - inotifywait: for continuous monitoring and real-time output of filesystem events. It is often used in shell scripts to trigger actions like deployments, backups, or log monitoring. - inotifywatch: gathers filesystem access statistics and outputs a summary count of events received on each file or directory. It is suitable for short-term monitoring to collect event statistics.
