tmux vs zellij — which terminal multiplexer?
Both split panes and keep sessions alive: the classic you configure yourself, or the modern one that teaches you its keys as you go.
On Debian/Ubuntu, most of these tools are also one sudo apt install away.
brew install tmux # macOS — or: sudo apt install tmux
tmux new -s work # try: new session named "work" (Ctrl-b % splits, Ctrl-b d detaches)
brew install zellij # install
zellij -s dev # try: start a session named "dev"
