# LibTmux::Server::kill_session

- **Module:** LibTmux
- **Package:** LibTmux
- **Language:** Perl
- **Kind:** method
- **Source:** https://github.com/libtmux/libtmux-perl/blob/352715a4fa66a96eed7763b90daaa536aa2f121d/packages/core/lib/LibTmux/Server.pm#L1070

```
sub kill_session($self, %args)
```

`kill_session(session => Session|session_id)`.

Destroy the selected [`LibTmux::Session`](/en/perl/latest/reference/libtmux-session/) and its links. Windows linked elsewhere can survive. Captured data remains local; later mutations through stale generation handles are checked.

Returns `undef` after command acceptance. Performs I/O; failures propagate through [`LibTmux::X`](/en/perl/latest/reference/libtmux-x/). Captured objects are not modified.


```perl
    $server->kill_session(session => $session);
```
