1.8.20.1 Install wont stop

hello all. I am VERY new to Asterisk and I have been installing on my Linux cloud server but have run into a problem. I went to test * out and see if the install had taken etc and got a warning saying modules.conf could not be found (still try to figure that part out) and then it gave me the CLI comand line. I can not exit from here. I have tried stop now and a few other variations with no luck. Any help would be appreciated… going INSANE and not slowly. Thank-you.

ignore that… figured it out… I’m sure there will be more!
