Getting the "fully qualified canonical domain name" in Linux server

Question

I'm following a guide on setting up SSO for SAP HANA. Part of the requirements are that I find the "fully qualified canonical domain name" of the HANA server I've created. I have access to the server via the command line. Is running the hostname command while logged in to the server (logged invia SSH) all I need to do to determine the FQCDN?

Answer 1

hostname -f (or --fqdn or --long) should return the fully qualified domain name.
