Use popen3

From gist.

def run_command(cmd_text)
  Open3.popen3(cmd_text) do |stdin, stdout, stderr, wait_thr|
    exit_status = wait_thr.value
    if exit_status != 0
      puts stderr.read
      abort
    else
      puts stdout.read
    end
  end
end

From article.

require 'open3'

cmd = 'git push'
Open3.popen3(cmd) do |stdin, stdout, stderr, wait_thr|
  puts "stdout is:" + stdout.read
  puts "stderr is:" + stderr.read
end
