# LibTmux::Server::set_title

- **Module:** LibTmux
- **Package:** LibTmux
- **Language:** Perl
- **Kind:** method
- **Source:** https://github.com/libtmux/libtmux-perl/blob/352715a4fa66a96eed7763b90daaa536aa2f121d/packages/core/lib/LibTmux/Server.pm#L1046

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

`set_title(pane => Pane|pane_id, title => string)`.

Set a [`LibTmux::Pane`](/en/perl/latest/reference/libtmux-pane/) title. Literal input is protected from format expansion; tmux's own title sanitization remains observable in a new [`LibTmux::Snapshot`](/en/perl/latest/reference/libtmux-snapshot/).

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->set_title(pane => $pane, title => 'build.v2');
```
