Killing processes which matches grep pattern

Recently I wan working on a script which automatically starts the set of scripts in background.  When I wanted to stop those scripts, I have written a small command which kills all processes at one shot which are matching the pattern. Here is the command

kill -9 `ps -eaf|grep "stat.sh"|grep -v grep | awk '{print $2}'`

Here 

stat.sh ==> is the pattern.

grep -v grep ==> avoid grep's process id

awk '{print $2}'` ==> prints second argument

I use this often in unix/linux.
