Hello,
Many thanks all for the help
Here is Dan revisited code and checks. Need some improvements like checking Windows and Ruby version.

String.encode needed? Why?
How do you colorize your code on the forum?

and code (thanks to Dan. I’ve got colorized code!)

def system_read(str_cmd)
      begin
        filename = nil
        raise('system_read(str_cmd). str_cmd must be a string.') unless str_cmd.is_a?(String)
        raise('system_read(str_cmd). str_cmd must not be empty string.') if str_cmd.length == 0
        str_data = IO::popen(str_cmd) {|io| io.read}.strip()
        bol_exit = ($?.exitstatus == 0)
        if str_data.empty? or !bol_exit
          filename = ENV['TMP'].encode('UTF-8').gsub('\\','/') + "/" + (Time.new.to_f * 1000).to_i.to_s
          bol_exit = system(str_cmd + " > " + filename)
          str_data = File.read(filename).strip()
        end
      return bol_exit, str_data
      rescue => e
        puts e.message
      ensure
        if filename && File::exist?(filename)
          File::delete(filename) rescue nil
        end
      end
    end

    bol_exit, str_data = system_read('echo "Hello world!"')
    puts "    with Sketchup " + Sketchup.version.split(".")[0]+"\n      "+
	bol_exit.to_s + ", ->" + str_data + "<-\n    end with"

now checks

    with Sketchup 17
      true, ->"Hello world!"<-
    end with
    with Sketchup 16
      true, ->"Hello world!"<-

    with Sketchup 16
      true, ->"Hello world!"<-
    end with
    with Sketchup 8
      true, ->"Hello world!"<-
    end with

all right. good news!
