Incorporating tmux in a terminal workflow

Published on 11^th March 2025 Estimated Reading Time: 2 minutes

As part of a recent workstation upgrade and subsequent AI explorations to see what runs on a GPU, I got to use tmux to display two panes within a terminal session on Linux Mint, each with output from a different system monitoring command; one of these was top for monitoring system processes in a more in-depth way. Some of that need has passed, yet I retain tmux and even set to open in a new terminal session by adding the following code to my .bashrc file:

if command -v tmux &> /dev/null && [ -z "$TMUX" ]; then
    tmux new
fi

This tests if tmux is installed and that this is not running in an existing tmux session before opening a new tmux session. You can also attach to an existing session or use a new default session if you like. That changes the second line of the above code to this:

tmux attach -t default || tmux new -s default

Wanting to have everything fresh in a new session, I decided against that. While I have gone away from using tmux panes for the moment, there is a cheat sheet that could have uses if I do, and another post elsewhere describes resizing the panes too, which came in very useful for that early dalliance while system monitoring.
