libinotifytools0 3.22.1.0-2 (amd64 binary) in ubuntu jammy

 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.
 .
 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.
