Update hostname in Mint Linux

A simple one liner here to update the hostname (computer name of Mint Linux 18).

I had to find out the name of the text editor installed. I typed, "text" in the launch bar, opened the text editor, selected: help, about. This told me the name was 'xed'

So open a terminal window and type

Sudo xed /etc/hosts

Which will open an administrative text editor.

Simply replace the host name with what you want, save and reboot.

Another method is simply to type sudo hostname - but that only TEMPORARILY changes your host name!

The method I mentioned first will do it permanently!
