I am referring to the following link:

An introduction to Udev: The Linux subsystem for managing device events

In this link, an example is shown demonstrating how udevadm can be instructed to invoke a script based on a state change induced by ACTION="add", implying a device is plugged into the system.

I would like to know whether there is a way to simulate this state change, without actually having to unplug and plug the device again into the system, so that I should be able to execute a script by means of udevadm by just reloading udevadm.

Appreciate your thoughts

TIA

You can create any event using udevadm trigger <device>. Default action is change, other actions can be specified using -c <action>. See udevadm manpage for more information.
