I like that a lot better than the "clever" awk I whipped up:

awk 'BEGIN { RS="}"; FS=","} /([:digit:].*)/ {print $2}'
/var/lib/rabbitmq/pids > $PIDFILE

BTW, I had to install the deb on another machine so I could get the
/etc/init.d script.
Would it be possible to include it in the binary generic unix server

Thanks! I am going to set this up today and will email back with any
modifications I have to make.
