kill all user processes

Hi there, i've been searching all over and i thought i had understood the way i should go to kill all the processes related to a user. But i'm getting more confused then i was.
By lunch time i have to make a database backup, and for that all the users shoul logout. The problem is that many users don't have the trouble logging out , so before i start the backup i have to kill them all. I've tryed some scripts , and tryed to adapt them to my needs, but all that i found would kill by process name , or using the pid.
I need some script that would ask me for the user to kill , and given the username it would kill all the processes running by tht user.
How can i do this?

i was trying to use this

printf "\n\nUsername to kill?"
read nUsername

[ "$nUsername" ] || exit

ps -u $nUsername | awk -v nUid="nUid" '
{
if ( $1 == nUid )
kill -9 $2
}'

sorry, no great knowleage about scripting
thanks

kill

KILL(1) 						      General Commands Manual							   KILL(1)

NAME

       kill, broke - print commands to kill processes

SYNOPSIS

       kill name

       broke

DESCRIPTION

       Kill  prints  commands  that  will cause all processes called name and owned by the current user to be terminated.  Use the send command of
       81/2(1), or pipe the output of kill into rc(1) to execute the commands.

       Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer,  if  heavy
       handed, kill, but is necessary if the offending process is ignoring notes.

       Broke  prints  commands	that  will  cause all processes in the Broken state and owned by the current user to go away.  When a process dies
       because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger.  Executing  the  commands
       printed by broke lets the system reclaim the resources used by the broken processes.

SOURCE
