# Commands

BRU is a simple command line tool (currently implemented as a bash script.) All it really does is help you properly set up the required ROS environment variables.

Here are the commands:

```
env     Display all relevant Environment variables
export  Display bash commands to export state
mode    Set running modes
name    Set name of Robot
robot   Control the attached robot remotely
status  Display current Bru sttings
```

## .bashrc set up

The most important part of BRU is the set up in the .bashrc script on computers, robots and vms. They all get it.

```
# Support for bru mode setter
export BRU_MY_IP=$(myip)
export BRU_VPN_IP=$(myvpnip)

# Setting for simulation mode
# $(bru mode sim)
# $(bru name roba -m $(myvpnip))

# Settings for a physical robot 
# $(bru mode real)
# $(bru name platform1 -m 100.107.118.103)
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://campus-rover.gitbook.io/lab-notebook/fiiva/bru/commands.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
