What is the purpose of the command udevadm monitor?
The purpose of the command 'udevadm monitor' is to listen to kernel events produced by a udev rule and print information to the console. It allows users to observe udev events and kernel uevents in real-time, which is useful for debugging and analyzing device events.
A is correct; "udevadm udevmonitor will print udev and kernel uevents to standard output. You can use it to analyze event timing by comparing the timestamps of the kernel uevent and the udev event. Usually udevmonitor is a symbolic link to udevadm. In some distributions, this symbolic link no longer exists. To access the monitor on these systems, use the command udevadm monitor" https://lpic2book.github.io/src/lpic2.201.3/?h=udevadm#udev
A - 100%
When you run udevadm monitor, it listens for udev events and displays information about these events in real-time on the terminal.
