# oz0 index refresh

> Fetch the trusted indexes again, or the one named.

For: Operators and developers looking up a command.

Fetch the trusted indexes again, or the one named. With --file, the server takes that copy of index.json instead of fetching it: a mirror, for a cluster that cannot reach the index. A copy is kept only if a key its root certified signed it, it has not expired, and it is not older than the version the cluster has seen; a lower version is refused as a rollback. hub: installs also refresh a copy older than 10 minutes.

Cluster admins may.

## Usage

```bash
oz0 index refresh [name] [flags]
```
