Hi Sudhindra, Depending on the needs/requirements of what you're trying to do, you could probably get away with exec'ing your ruby file in a subshell and direct output as needed.
Take a look at Kernel module backtics (http://www.ruby-doc.org/core/ classes/Kernel.html#M006001) and read up on various options regarding (sub)processes (altho old pickaxe book ... http://www.rubycentral.com/pickaxe/tut_threads.html). Simple example: $ cat sum.rb puts "#{ARGV[0].to_i} + #{ARGV[1].to_i} = #{ARGV[0].to_i + ARGV [1].to_i}" $ ruby sum.rb 4 5 4 + 5 = 9 $ irb > `ruby sum.rb 3 4 > sum_output.txt 2>&1` => "" > res = IO.read('sum_output.txt') => "3 + 4 = 7\n" Note however that using backtics you can directly capture the output of what was exec'd in the subshell if you want, instead of writing it to some file and then reading it back in: > res = `ruby sum.rb 3 4 2>&1`.chomp => "3 + 4 = 7" That said, I second Michael's hope-you-know-what-you're-doing.
