Hi,

Based on my understanding of the code, it looks impossible to execute a command that redirects stdout to a file for example - so;

command \> /tmp/myoutput won't work.

This is because of the line;

Open3.popen3(cmd) do |stdin, stdout, stderr|

Which I understand tells Ruby to capture the stdout of the executed command.

Is there any workaround available ?
