Script to start rails server on open port and open in Chrome

rsv

#!/bin/bash

PORT=3000
while [[ $(netstat -lnt | grep ":$PORT ") != "" ]]; do
        PORT=$(($PORT + 1))
done

rails server -p $PORT &
SERVEPID=$!

sleep 2.5

google-chrome http://localhost:$PORT

control_c()
{
        kill $SERVEPID
}

trap control_c SIGINT

wait

I save this file as ~/bin/rsv (with is in my $PATH) and chmod it to 755. Once that is done, I:

cd rails_project
rsv
