inotifywait provides an option to exclude directories from processing events. In operation mode you might have a large directory you don't want to include in monitoring. For details regarding the available events (modify, attrib.) check out the inotifywatch(1) manpage. srv/test/infoq/ CLOSE_WRITE,CLOSE article.txtĪs you can see you're notified about the changes just as soon as they happen. Inside the shell session running the inotifywait command you should notice: % echo TODO > /srv/test/infoq/article.txt While keeping the job running in another shell session we'll create a new directory, touch a new file and delete the file again: Beware: since -r was given, this may take a while! % inotifywait -rme modify,attrib,move,close_write,create,delete,delete_self /srv/test To check whether your own kernel version supports Inotify as well, you can run the following command: Nowadays being based on the fsnotify backend all major Linux distributions provide proper Inotify support out of the box. What's known as kqueue on BSD and Mac OS X provides an efficient way to trace actions in the filesystem on Linux in real-time. Inotify is a file change notification system in the Linux kernel, available since version 2.6.13. In this article we will walk through how to use Inotify to monitor directories and trigger alerts on changes and present tools you might want to add to your personal toolbox. A framework which fulfills that requirement is Inotify.

Sending notifications when the upload of a file to a server completesĪ common approach to doing this sort of change notification is file polling, however this tends to be inefficient for all but the most frequently-changed files (since you have a guaranteed I/O every X seconds) and can miss certain types of changes (e.g.Automatic triggering of backup processes.Monitoring overall disk usage on a partition.Tracking changes in critical system files.Notifying applications of changes in configuration files.The need to scan a given filesystem for changes is a fairly common one, and there are a variety of common tasks which require this, including: TEMASOFT FileMonitor can track file operations on Windows and Linux machines.Summary - or why should I monitor the filesystem at all?

Through low-level file tracking technology, FileMonitor can monitor file activity in real-time and can alert you if files have been changed.
