You can do what you would do manually:
root_dir=$(cd `dirname $0`/.. && pwd)
But probably you will like an easiest way. You don't need to change folder and print the current folder, just get the name you need and add the parent path:
root_dir=$(dirname $0)/..

And that string is the parent of your script seen from your current location (relative path). If you want and absolute path, you can tryroot_dir=$(readlink -f $(dirname $0)/..)
