...         cmd_args: t.List[t.Union[str, int]] = [cmd]
...         if self.socket_name:
...             cmd_args.insert(0, f"-L{self.socket_name}")
...         cmd_args.insert(0, "-f/dev/null")
...         return tmux_cmd(*cmd_args, *args)
...
...     default_option_scope = OptionScope.Server
```

```python

True
```
