Another approach

RXS = {
  /YOUR_REGEX/ => "THE NEW LINE",
  /YOUR_REGEX12/ => "THE NEW LINE12",
}

File.open("destination.txt", "w") do |out|
  File.foreach("original.txt") do |line|
    out.puts line

    RXS.each do |rx, add|
      if rx =~ line
        out.puts add
        break # remove this if you want output for all triggers
      end
    end
  end
end

Kind regards

robert
