```
server.Server.saveBuffer(name: : string, path: : string, options: : { readonly append?: boolean }) -> Promise<void>
```

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

`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.

## Example

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