I'm dynamically defining a module name from an argument passed on the cli, for example Required::Module::#{ARGV.first}
Is there any way to check if that module exists? Also, how would I run methods on it not knowing it's exact name?

Get the class if it exists:
dynamic_klass = "Required::Module::#{ARGV.first}".classify.safe_constantize
Call a method on the class if it does:
dynamic_klass.send("some_method") if dynamic_klass.present?
