Temporarily change Terminal/Bash prompt

It is possible to temporarily change the prompt that is appears on every line within macOS and other operating systems which present a bash style terminal. You may want to customise this during a demonstration or screenshare rather than showing off your computers hostname and username.

When you open Terminal in macOS, for example, you are operating a Z shell. Older versions of macOS used Bash.
​
​​By default, the prompt will show the username of the currently logged in user, followed by @ and the hostname of the computer you are using. 

To change this temporarily you can use export.
