Run commands with Aruba

As long as you've got the neccessary programs, libraries, runtime
environments, interpreters installed, it doesn't matter in which programming
language your commandline application is implemented. You can even use POSIX
standard tools like "printf".

Below you find some examples of the "Hello, Aruba!"-application implemented
with different programming languages and a single example for a POSIX
standard tool. This is NOT an exclusive list. Every commandline application
should run with aruba.

Background
Given
I use a fixture named "getting-started-app"
And
a file named "features/hello_aruba.feature" with: 
Feature: Getting Started With Aruba
  Scenario: First Run of Command
    Given I successfully run cli
    Then the output should contain:
    """
    Hello, Aruba!
    """
Scenarios
  1. Bash Program
  2. Bash Program run via bash
  3. Ruby Program
  4. Ruby Program via "ruby"
  5. Python Program
  6. Python Program via "python"
  7. Perl Program
  8. Perl Program via "perl"
  9. Java Program
  10. POSIX standard tools
