Root folder seems empty when SSH to EC2

I am trying to ssh to my EC2 instance in Amazon.

After reading some articles I have ran the following command:

ssh -i new_key.pem ec2-user@ec2-XX-XX-XX-XX.us-west-2.compute.amazonaws.com

it logged in, but the ~ folder is empty - only composer.phar file is there. when typing cd.. I get command not found.

What am I missing?
