i put this into /usr/local/bin/eunic and you can your server using eunic -s && eunic -N

eunic

#!/bin/bash
set -u
set -e
#change this below to your actual path.  If you another environemnt like staging, fucking change N to -e staging instead.
APP_PATH=/youpath/to/app/root
PID=$APP_PATH/tmp/pids/unicorn.pid
OLD_PID=$APP_PATH/tmp/pids/unicorn.pid.oldbin
UNICORN_COMMAND="unicorn_rails -c $APP_PATH/config/unicorn.rb -D"

while getopts ":nsNr" opt; do
case $opt in
    N)
            echo "Starting Unicorn in Production"
            unicorn_rails -E production -c $APP_PATH/config/unicorn.rb -D
            ;;
    n)
            echo "Starting Unicorn in Development"
            $UNICORN_COMMAND
            ;;
    s)
            echo "Stopping Unicorn"
            kill -15 `cat $PID`
            ;;
    r)
            echo "Reloading Unicorn if USR2 is enabled"
            kill -USR2 `cat $PID`
            if [ -s $OLD_PID ]

            then 
                kill -WINCH `cat $OLD_PID` && kill -QUIT `cat $OLD_PID`
            fi
            ;;
    ?)
            echo "Usage: -n [start dev mode] | -N [ start Production mode] | -r [restart/reload] | -s [stop unicorn]"
            exit 1
            ;;
esac
done

i hope those are comments in bash too, but make sure you chmod +x /usr/local/bin/eunic after you create this file on your server.
