Hello haukex,

Thank your for your time and all the links that you provided me. Yes I also notice the difference between qx and qw. I also was reading this system() and qx comparison, which someone might also find it useful.

Never the less thank you again and hopefully I will continue experimenting and I will be able to see the differences in shell. I need to test the commands on both OS to see what is happening.
