- install.sh: deploy_tmux_config runs on both OSes after the bashrc (gated on tmux) - tmux.conf: clipboard via if-shell (pbcopy on macOS, tmux buffer + OSC 52 elsewhere) - bashrc-linux exports XDG_CACHE_HOME like the macOS rc files - prefix i = side-by-side split, prefix - = stacked split (h/j/k/l kept) - verified in an Ubuntu 24.04 container (tmux 3.4): deploy, bindings, split, plugins, libtmux
