libtmux.Server.detach_all_clients(
    self,
    keep_client: str | None = None,
    shell_command: str | None = None,
) -> None
```

Detach every client on this server via [`$ tmux detach-client -a`](/en/tmux/latest/manual/detach-client/).

tmux's ``-a`` always preserves one client; when *keep_client* is
omitted, the most-recently-active client survives.

## Examples

```python
>>> with control_mode() as ctl:
...     server.detach_all_clients(keep_client=ctl.client_name)
```

## Parameters

- `keep_client` (`str | None`): Client to preserve (``-t`` flag). All other clients on the
server, regardless of which session they are attached to,
are detached.
- `shell_command` (`str | None`): Run a shell command on the detached client(s) after detach
(``-E`` flag).
