I am Using SCo UNIX ver 5 and using korn shell. When I kill a process ID of user login, the process gets killed but the who -u command output shows the login name ,tty, and PID of the killed process along with other active process. The details of the killed process is listed on the who -u output and the idle time is also incremented even though no such process exists.This development took place 2 weeks before. I suspect that some file related to who output is not refreshed. I wish to know what files are altered on killing the process and how to rectify the same?
