Most of the hackers use linux is that true?

yeah it is true.they use it as it lets them access all the open ports on a computer and it gets round windows security.

the majority of hackers like unix os than others and in writing mode than a graphic one as windows or the gnome interface in linux as well!!So linux can be considered the modern evolution of the old unix systems and considering that many hackers grew up more on unix than windows or macos they prefer now linux!!surely linux for this point of view is much better..have many instruments if you like programming and also give you a better knowledge about an operating system than windows or others!!So yes i think they like more /unix/linux!!

I have never heard of that before. I wander if it is true also? I think hackers will use just about anything they can get their hands on. I really do not think they choose certain things to use because it would be easier for them to get caught.

If you mean someone who is really skilled with computer programming, nowadays they usually own multiple machines running multiple operating systems. The most typical combo these days is Mac laptop for personal use, Linux machine for programming, and Windows when necessary, or for games.
