shell script to read ps -e output and determine process double processes.

hi. I just noticed doing ps -e that there was three instances of mplayer running. I am thinking of making a script to search the output of pe -e and determine if there are multiples of a program running. i am not sure as to how i can go about storing the output in a variable to make it easy to test against. Can anyone steer me in the right direction? thanks for your replies in advance.

simple approach would be to grep the results in a count based on line and run test on it

ps -e | grep mplayer | wc -l

store as variable and run test on it like

i=$(ps -e | grep mplayer | wc l)
if [ i -gt 1 ]
then
do
don
