How to get ALL bash history with a single command?

The history command as well as the upper arrow key gives you the bash history of the terminal you type from. If you have several opened terminals like several windows and/or non graphic terminals with Ctrl-F1 to Crtl-F6, you have to type from each and every terminal in order to get all your history.

Is there any way to get the history of all terminals from a single terminal?

I had thought my .bashrc contained the answer for you but when I searched on "bash combine history" and came up with this link that shows how to do it, it came up with one extra piece I was missing the prompt part to do a re-read every time.

With default settings, there is no single location that tracks the history for all your bash shells. Each bash process keeps its own history internally, initializing that list with the last $HISTSIZE lines from $HISTFILE. When an interactive shell exits, the last $HISTSIZE lines are copied from the history list to $HISTFILE. Unless the histappend shell option is set (by default it is not) an existing $HISTFILE is overwritten.
