Thanks for your reply. I'm newbie, and yes, I tried to print out the $cmd, it print out nothing. Is that possible to call subroutine from the $ec->configure(-command => ) line?

I wonder how people do if they want to execute external program which read wrapper (text in my case) with this module, as for now my end it only works with single liner command.
