who and finger reporting logout users
 

Ive been having issues with who and finger reporting users that are no longer logged in. I tryed doing pgrep -u (user) to figure out what to kill ... but it doesnt return any pids. Im not sure what caused this in the first place, but i cant manage to get it to go away without rebooting the machine. (these users were logged in through ssh as well as tty1-4). Thanks.

man ps could help you perform wonders. Alternately, if you are an ncurses kinda dude, you could use whowatch or a similar program. I find it useful for such instances. ps -U username is great as well. Hope that points you in the right direction.
