## What Does This Command Do?

The `reclaim` command performs three cleanup operations to free up disk space in your HANA database:

1. **LOB Space Reclamation**: Frees up unused space in LOB (Large Object) storage
2. **Log Reclamation**: Reclaims space from transaction logs that are no longer needed
3. **Data Volume Defragmentation**: Defragments data volume 105 to optimize storage

This command is particularly useful after large delete operations or when disk space is running low.

## Examples

### Basic Usage

```bash
hana-cli reclaim
```

Execute all three reclaim operations with default connection.

### Using Admin Connection

```bash
hana-cli reclaim --admin
```

Execute reclaim operations using admin credentials for full system access.

### With Custom Connection

```bash
hana-cli reclaim --conn my-db-connection.json
```

Execute reclaim operations using a custom connection file.

### Quiet Mode for Scripting

```bash
hana-cli reclaim --quiet
```

Run reclaim operations with minimal output for use in scripts.
