How to kill and logout a user in Linux

You can check who is logged in to a Linux system by executing
who or w commands
and then you can get the user PID
ps aux | grep username or tty
and kill it
kill -KILL PID
or you can use pkill command and kill the user by its username
pkill -KILL -u username
It would be nice to send the users a warning message before logging them out.
