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 ~/.bashrc shopt -s histappend shopt -s histreedit shopt -s histverify HISTCONTROL='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.
