[tmux] Handle history in tmux sessions

 

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.
