Open database manager (mysql is the only one supported right now) based on parameters.yml file.

database.sh

#!/bin/bash

## Usage
## database.sh /path/parameters.yml
## or if you are in symfony root directory
## database.sh

if [ -z $1 ]
then
    if [ -f "app/config/parameters.yml" ]
	then
		PARAMETERS="app/config/parameters.yml"
	else
		echo "Can not locate parameters.yml file"
	fi
else
	if [ -f $1 ]
	then
		PARAMETERS=$1
	else
		echo "Given parameters.yml path does not exists"
	fi
fi

DRIVER=`cat $PARAMETERS | grep database_driver | awk '{print $2}'`
PASSWORD=`cat $PARAMETERS | grep database_password | awk '{print $2}'`
USER=`cat $PARAMETERS | grep database_user | awk '{print $2}'`
HOST=`cat $PARAMETERS | grep database_host | awk '{print $2}'`
PORT=`cat $PARAMETERS | grep database_port | awk '{print $2}'`
NAME=`cat $PARAMETERS | grep database_name | awk '{print $2}'`

if [ 'pdo_mysql' = $DRIVER ]
then
	if [ 'null' = $PORT ]
	then
		PORT='3306'
	fi

	mysql -u$USER -p$PASSWORD -h$HOST -P$PORT $NAME
else
	echo -e "Unknown driver $DRIVER"
