ARGV
Any command-line arguments after the program filename are
available to your Ruby program in the global array ARGV.
For instance, invoking Ruby as
% ruby -w ptest "Hello World" a1 1.6180

yields an ARGV array containing ["Hello World", a1, 1.6180]. There's a gotcha here for all
you C programmers---
ARGV[0] is the first argument to the program, not the program name.
The name of the current program is available in the global variable $0.
