[Cucumber] Is there any way that I can use variable in a file to execute CLI in Cucumber/Aruba?

Is there any way that I can use variable to execute CLI in Cucumber/Aruba?
For example:
A file named "features/support/variables.rb" with:
Copy
ENV['LONG_LONG_VARIABLE'] = '1'

Feature: Variable
Scenario: Run command
When I run echo $LONG_LONG_VARIABLE
Then the output should contain:
"""
1
"""
