tmux sessions

A tmux session is a persistent workspace that keeps your terminal processes running in the background even after you disconnect.

Tmux sessions decouple your terminal applications from the physical window (the client). When you run a command like 'tmux new -s dev' on a remote server, that session lives in the tmux server process. You can detach using 'Ctrl+b d' to close your laptop, then reattach later with 'tmux attach -t dev' to find your compilers, editors, and logs exactly where you left them. This persistence is vital for long running tasks (like database migrations or large builds) and protects your work against sudden SSH connection drops. Within a single session, you can manage multiple windows and panes to organize complex workflows without opening dozens of separate terminal tabs.
