# openlabel watch

> List the saved claims a label change touches.

```sh theme={null}
openlabel watch [folder]
```

Reads every `*.check.json` that [`check --save`](https://au-2a4a5dc8.mintlify.site/cli/check) left in `folder` and its subfolders (default: the current directory). For each piece whose label has a newer version, it diffs the version the piece was checked against with the current one and lists the impacts. File names are shown relative to `folder`.

| Option | Description |
| - | - |
| `--json` | Print the result as JSON: `pieces` (each with its diff and impacts) and `current` |

Exits 0 when nothing is affected and 1 when anything is. See [Watch](https://au-2a4a5dc8.mintlify.site/tools/watch.md) for the kinds of impact.
