tmux

To keep long-running shell commands alive after a session timeout, run them inside named tmux sessions that persist independently. These durable sessions survive shell disconnects, allowing you to safely detach and re-attach later without losing ongoing process state.

You can share ongoing dev server workflows across multiple Codex threads by using shared tmux sessions. This enables coordination by allowing multiple threads to attach to the same stable session name and monitor the same interactive shell output simultaneously.

The best way to monitor build tasks and log tails across threads is running them inside named tmux sessions. This approach captures output safely and enables you to attach, detach, and inspect long-running processes from any thread while preserving window layouts.

Tmux supports managing multiple windows and panes to organize concurrent work within durable sessions. You can create dedicated or shared sessions, manage window layouts, and safely invoke commands with output capture for interactive shell tasks.

You capture and inspect output from a long-running command by running it inside a named tmux session using safe invocation patterns. This allows you to monitor interactive logs and capture process output while detaching and re-attaching across threads without interrupting execution.
