Full Discussion: Notification as popups when a file being written
Top Forums Shell Programming and Scripting Notification as popups when a file being written Post 302678635 by alister on Sunday 29th of July 2012 04:16:10 AM

Centos alone isn't very helpful. The output of uname -a would have been better.

If it's supported by your kernel, you can use inotify.

inotify(7): monitoring file system events - Linux man page

For shell script use, inotifywait from inotify-tools may be of interest.

inotifywait(1) - Linux man page

Popular scripting languages also provide their own inotify interfaces.

Beyond watching the filesystem, as for delivering the gui notification itself, that probably depends on the desktop environment you're using and/or if there's a specific daemon with which to communicate.
