hello razmeth and welcome to the monastery

the key concept behind your question is multiplexing.
Follow in your production code the wiser advices you already received but, in the case you want to explore that way and reinvent the wheel (see my sgnature..) you can have a look at my attempt to do exactly the same thing: Multiplexing log output: Log4perl of the poors
Also Loops's attempt at Output to STDOUT and print last line to console is reach of useful hints.
