Force the logon user in the nux System

Platform: RHEL5.4

First, run the "w" command to view the logon user information, then run the "pkill-kill-t pts/x" command to kick the user (indicating that the user who uses pkill to send the kill signal to kill the terminal is pts/x and can kick multiple users at the same time ), only root users can play. example:

# W
