Subject: Re: Pass arguments to 'require'

Ruby takes its arguments from a global array called ARGV. That array
is special because it is initialized by the interpreter, buy from then
on it is a regular mutable array.

In particular you can modify it:

  def with_argv(*argv)
    original_argv = ARGV.dup
    ARGV.replace(argv)
    yield
    ARGV.replace(original_argv)
  end

You would use that method this way:

  with_argv(1, 2, 3) do
    require '/opt/ruby/script1'
  end

Not that it is a good practice, you normall would invoke the scripts
using #system or whatever, but since you say you are not a programmer
that would fit into your current model if you don't feel confident to
explore system.
