A way to view full output of background terminals #16935
Description
What variant of Codex are you using?
CLI
What feature would you like to see?
What issue are you seeing?
I’m using Codex CLI to run long-running ML jobs (e.g., training / rollout), and the current /ps command only shows a summarized preview (last few lines) of background terminals.
There is currently no clear way to view the full live output of a running background task.
What is the expected behavior?
There should be a way to:
- Attach to a background terminal (similar to
tmux attach) - Or expand
/psinto a full log view - Or stream full stdout of a selected job
Why is this important?
For long-running workloads, logs are critical for:
- debugging
- monitoring progress
- detecting failures early
The current summarized view is not sufficient for these use cases.
Suggested solutions
- Add
/attach <job_id>to open full terminal view - Add
/logs <job_id>to stream full output - Or allow toggling between "preview" and "full" mode in
/ps
Additional context
This feels like a limitation compared to tools like tmux/screen, where full session output is accessible.
Better observability for background tasks would significantly improve the developer experience when using Codex CLI.
