I am newbie to this forum.
I am in search of tutorials/ books material which explores in-depth of how Operating system works in relate to Linux commands and utilities.
All I am in need of materials which can give me insight into how booting process goes, kernel functionality,paging, virtualization stuffs, OS to Storage connectivity etc etc stuffs.
Anyone who can recommend me the same.

Note: I am working as System Admin in Linux for the past 3 years and have no knowledge in C/C++. So the Material should be good enough for me to understand.

You can learn a lot about the boot process from the man pages.
man boot.

Use the apropos (man apropos) to discover relevant manuals.
learn how to read these - it takes practise.

Simon..I think you respect little man a lot !!

I loved reading this line:


$man boot

".... When the kernel is loaded, it initializes the devices (via their
drivers), starts the swapper (it is a "kernel process", called kswapd
in modern Linux kernels), and mounts the root file system (/).

Some of the parameters that may be passed to the kernel relate to
these activities (e.g: You can override the default root file system).
For further information on Linux kernel parameters read bootparam(7).

Only then the kernel creates the first (user land) process which is
numbered 1. This process executes the program /sbin/init, passing any
parameters that weren't handled by the kernel already..."

Thanks Simon..for this little but elaborate command.

The manuals vary a lot - but man boot has one of the better short overviews. Also look at the related pages at the bottom if you feel you need more detail on specifics.

The info command can provide more detailed manuals too.
But for me, apropos has been the most educational command - you don't even need to know what the actual utility is called - apropos a guess and it'll be in the list.

Reading tutorials, and helping other people are the best ways to learn though.
