Rake / Rspec: How to suppress / quiet / silent the first output line showing the command with --pattern ?

Problem:

If I run ServerSpec (based on RSpec) through Rake with one of the following commands:

• rake
• rake spec
• rake spec:all
• rake spec:<host>
• bundle exec rake
• ...

Rake prints the command it executes to stdout before the serverspec output:

/usr/bin/ruby1.9.1 -I/var/lib/gems/1.9.1/gems/rspec-core-3.1.6/lib:/var/lib/gems/1.9.1/gems/rspec-support-3.1.2/lib /var/lib/gems/1.9.1/gems/rspec-core-3.1.6/exe/rspec --pattern spec/<host>/\*_spec.rb

If I pass the target host manually to rspec like this ...

TARGET_HOST=<host> rspec

... the line does NOT show up.

Question:

How can I prevent Rake from outputting this line / the command?

I'm using the default Rakefile generated by serverspec-init.

require 'rake'require 'rspec/core/rake_task'task :spec    => 'spec:all'task :default => :specnamespace :spec do  targets = []  Dir.glob('./spec/*').each do |dir|    next unless File.directory?(dir)    targets << File.basename(dir)  end  task :all     => targets  task :default => :all  targets.each do |target|    desc "Run serverspec tests to #{target}"    RSpec::Core::RakeTask.new(target.to_sym) do |t|      ENV['TARGET_HOST'] = target      t.pattern = "spec/#{target}/*_spec.rb"    end  endend
