Puppet

ralsh can only query resources, it cannot modify them:

$ ralsh user foo ensure=present
/opt/local/lib/ruby/site_ruby/1.8/puppet/resource.rb:158:in `send': undefined method `ensure=' for # (NoMethodError)
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/resource.rb:158:in `initialize'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/resource.rb:156:in `each'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/resource.rb:156:in `initialize'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application/resource.rb:86:in `new'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application/resource.rb:86:in `main'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application.rb:300:in `run_command'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application.rb:292:in `run'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application.rb:390:in `exit_on_fail'
    from /opt/local/lib/ruby/site_ruby/1.8/puppet/application.rb:292:in `run'
    from /opt/local/bin/ralsh:90

I see consistent errors when trying to create all kinds of resources.
