Complete Ramblings

We recently upgraded from rubygems 0.9.x to 1.2.0. Unfortunately, there doesn’t appear to be a working service init script for this new version, so I had to hand-craft a basic one to start/stop the service. You’ll find it below in all its glory (and probably under/incorrectly-implemented as I am in no way a linux guru, nor do I intend to be). It works for my use however, maybe it’ll help you.

pid=$(ps ax -o pid,command | grep “gem server” | grep daemon | awk ‘{print $1}’)

echo “gem server already running : PID $pid”

stop() {
pid=$(ps ax -o pid,command | grep “gem server” | grep daemon | awk ‘{print $1}’)
