inotify-tools 3.22.1.0-2 source package in Ubuntu

 inotify (inode notify) is a Linux kernel subsystem that monitors events in
 filesystems and reports those events to applications in real time via API.
 .
 inotify can be used to monitor individual files or directories. When a
 directory is monitored, inotify will return events for the directory itself
 and for files inside the directory.
 .
 inotify-tools is a set of command-line programs for Linux providing a simple
 interface to inotify. These programs can be used to monitor and act upon
 filesystem events. inotify-tools consists of four utilities: inotifywait,
 inotifywatch, fsnotifywait and fsnotifywatch.
 .
 inotifywait efficiently waits for changes to files, making it appropriate
 for use in shell scripts.
 .
 inotifywatch collects filesystem usage statistics and outputs counts of each
 inotify event.
 .
 fsnotifywait and fsnotifywatch are similar to inotifywait and inotifywatch,
 but they are using Linux's fanotify(7) interface by default. The fanotify API
 also provides notification and interception of filesystem events. Additional
 capabilities compared to the inotify(7) API include the ability to monitor
 all of the objects in a mounted filesystem, the ability to make access
 permission decisions, and the possibility to read or modify files before
 access by other applications.
 .
 inotify-tools is also useful for security activities in firewall systems or
 to detect changes and injections of new files in webservers by intruders.

 .
 libinotifytools is a thin layer on top of the kernel interface which makes
 it easy to set up watches on many files at once, read events without having
 to deal with low-level I/O and several utility functions for inotify-related
 string formatting.
