starts completely.
I have explore and find popen4 gem which provides this facility.
I have installed a gem but there is some problem while executing the ruby
program.

from <internal:lib/rubygems/custom_require>:33:in `rescue in
require'
from <internal:lib/rubygems/custom_require>:29:in `require'
from sample2.rb:2:in `<main>'*
