Hello shell script gurus. I'm sure I'm doing this the hard way...so if

I'm trying to write a shell script that will only run if it's not
running already, and if it is running, kill the other process. ie:
if ( other copy of me already running)
kill both myself and other copy
else
do some stuff
fi
I imagine you'll want something involving "echo $$ >myscript.pid" and then
perhaps "ps -a | grep `cat myscript.pid` | grep myscript && kill `cat
myscript.pid` && exit"
