Somehow my main Linux Mint-Cinnamon box got an inappropriate name. I have no idea how it happened but I decided to change it. The first site I visited for the knowhow was named "How to change the Linux hostname". I read the whole page and still didn't have a clue. It was all gibberish to me. Next site I visited was totally different. It told step by step how to do it and explained before hand that the hostname is stored in a file called "hostname". To change it you simply edit said file. Nothing could be simpler. So I went back and reread the first site. I still don't have a clue what they were going on about. Since the answer was so simple, why all the rigmarole and irrelevant gibberish? That's the way it is in the Linux universe, there are answers and there is gibberish. Why gibberish exists is known only by the gods. Amen.
