async output(): Promise<string>
```

What the program has printed so far, as its terminal shows it.

Scrollback is included and wrapped lines are joined. Tabs and trailing
spaces are kept; colors and cursor movement are applied rather than
returned.

## Examples

```ts
await using program = await server.spawn(["echo", "hello"]);
await program.wait();
await program.output(); // "hello"
```
