Installation

For commands that return output in json format

# pipeline.yaml
- implementation: nodestream_plugin_shell:Shell
  arguments:
    command: curl
    arguments:
      - https://example.com/api/data/json
    options: 
      X: GET
      header: "Accept: application/json"
    ignore_stdout: false #Provide json output from command to next step in pipeline.
