```
saveBuffer(
  name: string,
  path: string,
  options?: SaveBufferOptions,
): Promise<void>
```

Write a paste buffer to a file instead of reading it back.

[`showBuffer`](/en/ts/latest/reference/server-server-showbuffer/) returns the contents through this process; for a large buffer
that means holding it in memory to put it somewhere else. tmux writes the
file itself, on the machine tmux is running on.

## Examples

```ts
await server.saveBuffer("captured", "/tmp/build.log");
```

## Parameters

- `name` (`string`)
- `path` (`string`)
- `options?` (`SaveBufferOptions`)

## tmux command

The tmux commands behind `saveBuffer`.

- [`save-buffer`](/en/tmux/latest/manual/save-buffer/)

## tmux C API

The C declarations in tmux that implement these commands.

- [`cmd_save_buffer_entry`](/en/tmux/latest/reference/c-variable-cmd_save_buffer_entry/) (attribute)
- [`cmd_save_buffer_exec`](/en/tmux/latest/reference/c-function-cmd-save-buffer-c-cmd_save_buffer_exec/) (function)
