How to access the settings.js file for Node-Red on Cerbo GX

Hello I am trying to enable persistent data storage for Node-Red on my Cerbo GX. I have enabled superuser, set the root password and can access via Putty, but cannot find my way to the directory with the settings.js file. I am sitting at root@einstein:~ Can anyone tell me the specific commands to get to the right place? I have tried the standard dir command but that is not recognised Thanks Simon
