## envVars(): Dictionary<String>

Returns all the environment variables defined in the host system as an array of strings.

### Example

This example returns a Mac command console (`SHELL`) path. `SHELL` is one of the standard Mac
environment variables. To return all the environment variables, you can use `dw::System::envVars()`.

#### Source

```DataWeave
%dw 2.0
import dw::System
output application/json
---
{ "envVars" : dw::System::envVars().SHELL }
```

#### Output

```JSON
{ "envVars": "/bin/bash" }
```
