Linux is an operating system, like Windows. It allows you to use your computer. Nobody says "I need to learn Windows", do they? If you want to learn all about Linux to the level of creating your own distro or rewriting a kernel, or creating applications, you are not going to be able to do that on a forum or by email. You do it by being determined, enquiring, resourceful and hardworking.
If you want to "learn Linux" so you can get a job, maybe you should get books about Bash scripting, perl, C programming, networking, Ruby, the Linux kernel, system configuration, embedded Linux, and stuff like that.
I do not think you should be asking on a forum. You should be reading books and enrolling in college courses.
This attitude will
never work:
PLZ .. someone has to guide me step by step towards learning linux...
