In this lesson, we‘ll look at how to manage your history between tmux sessions, and ensure that your setup preserves your bash history between multiple windows. By adding a special PROMPT_COMMAND to your .bashrc, you can update and reload your history after every command, regardless of if you‘re in a different session, window, or tab.

First we need to edit our .bashrc file:

vim ~/.bashrcshopt -s histappendshopt -s histreeditshopt -s histverifyHISTCONTROL=‘ignoreboth‘PROMPT_COMMAND="history -a;history -c;history -r; $PROMPT_COMMAND"

Save it, then in each our tmux window, we source to it:

source ~/.bashrc

Now, each command we type are shared in each tab window.
