# snapdir verify-cache

Verify the integrity of the local cache.

`verify-cache` checks every object in the local cache against its content
address, detecting corruption across all staged snapshots at once. See
[Integrity](../concepts/integrity.md).

## Usage

```text
snapdir verify-cache [OPTIONS]
```

### Options

`verify-cache` takes no positional arguments. It accepts the
[global options](overview.md#global-options); the most relevant are `--cache-dir`
and `--purge` (drop objects with invalid checksums).

## Examples

Verify the default cache:

```console
snapdir verify-cache
```

Verify a specific cache directory and purge corrupt objects:

```console
snapdir verify-cache --cache-dir /var/snapdir/cache --purge
```
