# Hello

> Validate CLI installation and Lager Box connection

Quick command to validate your CLI installation, Lager Box connection, and display the box version.

## Syntax

```bash theme={null}
lager hello [OPTIONS]
```

## Options

| Option       | Description                 |
| ------------ | --------------------------- |
| `--box TEXT` | Lagerbox name or IP address |
| `--help`     | Show help message and exit  |

***

## Usage

```bash theme={null}
# Basic hello command
lager hello

# Hello with specific Lager Box
lager hello --box my-lager-box

# Hello with Lager Box IP
lager hello --box <BOX_IP>
```

***

## Output

The hello command displays a success message along with the Lager Box version:

```bash theme={null}
$ lager hello --box my-lager-box
Hello from my-lager-box!
Version: 0.3.22
```

If the box version cannot be determined (older box software that does not support version reporting), the version is shown as unknown:

```
$ lager hello --box old-box
Hello from old-box!
Version: Unknown
```

***

## Examples

```bash theme={null}
# Verify connectivity after initial setup
lager hello --box my-lager-box

# Quick check that default box is reachable
lager defaults add --box my-lager-box
lager hello

# Check version of a specific box
lager hello --box lab-gw
```

***

## Notes

* Simple validation command to test CLI installation
* Verifies connectivity to the Lager Box
* Displays the Lager Box software version by querying the `/cli-version` endpoint
* Useful for troubleshooting connection issues
* No arguments required when a default box is set
* Returns success message when connection is working
