The "sudo udevadm monitor --kernel" command is used to monitor and display events related to the kernel device manager (udev) in real-time with root privileges.

Here's a breakdown of the command:

• "sudo" is a command in Linux/Unix systems that allows a user to execute commands with superuser (root) privileges. It prompts the user to enter their password before executing the command.

• "udevadm" is a command-line utility for managing dynamic device nodes in the Linux kernel. It is used to control the udev system, which is responsible for detecting and creating device nodes for hardware devices.

• "monitor" is an option/argument for the "udevadm" command. It instructs the utility to monitor and display events.

• "--kernel" is another option/argument for the "udevadm" command used to specify that events related to the kernel should be monitored. These events include device addition, removal, and other related changes.

So, when you run the "sudo udevadm monitor --kernel" command, it starts monitoring and displaying udev events related to the kernel. This can be useful for troubleshooting hardware devices, understanding device changes, or observing the effects of certain actions on the system.
