"I am indebted to Eli Dow of IBM who wrote an earlier version of this article, prior to the final integration of inotify in the Linux kernel. In particular, the sample code available in the Download section is still based heavily on Eli's original sample code.

"Introducing inotify

"File system event monitoring is essential for many types of programs ranging from file managers to security tools. Since the Linux 2.6.13 kernel, Linux has included inotify, which allows a monitoring program to open a single file descriptor and watch one or more files or directories for a specified set of events, such as open, close, move/rename, delete, create or change attributes. Some enhancements have been made in later kernels, so check your kernel level before depending on those features.

"In this article, you will learn how to use inotify functions for a simple monitoring application. Download the sample code and compile it on your system to explore further."
