I want to learn Linux in depth.
I have some background in Java and C, but know nothing about operating system kernel, memory management, kernel processes and so on...
I would like to find some book with samples of code, deep , detailed descriptions.
One book I have is O'Reilly - Understanding The Linux Kernel - 2Nd Edition.
It is very good book, but it almost has not real code samples - a bit abstract for me...
Please, advise!
It’s almost does not matter what distribution it will be..
I like RH, SUSE ...

What you think : which way is better to learn OS(Linux), start from shells and then learn kernel or start from OS principals first?

start with OS principles first, then make your own shell scipts to do small things
so you can see how and why they work.

you should go thru and read the documentation directory in /usr/src/linux
there is a lot of info about the kernel and how to configure it for your specific
needs.............
