```
server.Server.cmd(command: : string, args: : readonly string[] = [], options: : CmdOptions) -> Promise<readonly string[]>
```

Run a tmux command this package does not model.

tmux has many more commands than any wrapper types. Rather than leaving a
caller to build their own subprocess — and reproduce the socket, the
environment, the deadline, and the error handling — this runs one through
the same path every other operation uses.

Failure raises {@link TmuxCommandError} like any other command, carrying
tmux's own stderr.

## Example

```ts
await server.cmd("list-keys", ["-T", "copy-mode"]);
```
