libtmux.Window.cmd(
    self,
    cmd: str,
    args: t.Any,
    target: str | int | None = None,
) -> tmux_cmd
```

Execute tmux subcommand within window context.

Automatically binds target by adding  ``-t`` for object's window ID to the
command. Pass ``target`` to keyword arguments to override.

## Examples

Create a pane from a window:

```python
>>> window.cmd('split-window', '-P', '-F#{pane_id}').stdout[0]
'%...'
```

Magic, directly to a `Pane`:

```python
>>> Pane.from_pane_id(pane_id=session.cmd(
... 'split-window', '-P', '-F#{pane_id}').stdout[0], server=session.server)
Pane(%... Window(@... ...:..., Session($1 libtmux_...)))
```

## Parameters

- `cmd` (`str`)
- `args` (`t.Any`)
- `target` (`str | int | None`): Optional custom target override. By default, the target is the window ID.

## Returns

:meth:`server.cmd`
