Thanks Massimo, you were great's people.. 1. if we read from file resulted from redirected stdout, i think that we get complete output finally, not ongoing process output ?? that was right, Massimo ?? correct me if i'm wrong ..
2. if we are using popen (popen2 or whatever), first arguments was cmd.. i think that cmd was external program or script, not function inside controller.. is true like that ? i don't want use external script/helper.. is it possible ?
