As Jamie already showed, you can pass parameters to tasks with the -s flag. I want to show you how you additionally can use a default value.

If you want to work with default values, you have to use fetch instead of ||= or checking for nil:

namespace :logs do
  task :tail do
    file = fetch(:file, 'production') # sets 'production' as default value
    puts "I would use #{file}.log now"
  end
end

You can either run this task by (uses the default value production for file)

$ cap logs:tail

or (uses the value cron for file

$ cap logs:tail -s file=cron
