this question has answer here:

• what (unary) * operator in ruby code? 3 answers

what args mean, , different between , argv if there difference?

 def puts_two(*args)     arg1, arg2 = args     puts "arg1: #{arg1}, arg2: #{arg2}"     end 

argv special variable in ruby. contains arguments passed script on command line. example, if write following code in file called test.rb:

argv.each |a|     puts end 

and call this

c:\> ruby test.rb 1 2 

will display

one 2 

in code posted, *args indicates method accepts variable number of arguments in array called args. have been called want (following ruby naming rules, of course).

so in case, args totally unrelated argv.
