These are quite different tools but yes, you can use Ruby like them
most of the time.  Please also have a look at command line parameters
of the Ruby interpreter (ruby -h).

This does not look like an SQL INSERT statement, what is it?

Not sure what exactly you are trying to do.  For the loading part
here's another variant:

h = {}

File.open "f1.txt" do |io1|
  File.open "f2.txt" do |io2|
    io1.zip io2 do |k,v|
      h[k.chomp] = v.chomp
    end
  end
end

p h

Well, if you tell us what exactly you are trying to achieve.  At least
to me it's not fully clear.

Kind regards
