Ubuntu setting hostname correctly?

I used the hostname command to set my host name. I think its working because when I type the command "hostname" with no arugments it returns the hostname that I set.

However when I type this "echo $hostname" I get a blank line returned. Why is that happening?

This is correct behavior. it is due to the fact that hostname is a program that will return your hostname and $hostname is a variable that you have not loaded (there is nothing associated to it). so an unloaded variable has no response or blank.

OK so how do I "load" the hostname variable?

you don't need to, the hostname variable is for programming/scripts... you hostname IS set and set correctly. the proper test (in Ubuntu) is to use the command "hostname" not $hostname.
