## Examples
### Running Cabana in Demo Mode
To run Cabana using a built-in demo route, use the following command:
```shell
cabana --demo
```
### Loading a Specific Route
To load a specific route for replay, provide the route as an argument:
```shell
cabana "a2a0ccea32023010|2023-07-27--13-01-19"
```
Replace "0ccea32023010|2023-07-27--13-01-19" with your desired route identifier.
### Running Cabana with multiple cameras
To run Cabana with multiple cameras, use the following command:
```shell
cabana "a2a0ccea32023010|2023-07-27--13-01-19" --dcam --ecam
```
### Streaming CAN Messages from a comma Device
[SSH into your device](https://github.com/commaai/openpilot/wiki/SSH) and start the bridge with the following command:
```shell
cd /data/openpilot/cereal/messaging/
./bridge &
```
Then Run Cabana with the device's IP address:
```shell
cabana --stream <ipaddress>
```
Replace &lt;ipaddress&gt; with your comma device's IP address.
While streaming from the device, Cabana will log the CAN messages to a local directory. By default, this directory is ~/cabana_live_stream/. You can change the log directory in Cabana by navigating to menu -> tools -> settings.
After disconnecting from the device, you can replay the logged CAN messages from the stream selector dialog -> browse local route.
### Streaming CAN Messages from Panda
To read CAN messages from a connected Panda, use the following command:
```shell
cabana --panda
```
### Using the Stream Selector Dialog
If you run Cabana without any arguments, a stream selector dialog will pop up, allowing you to choose the stream.
```shell
cabana
```
