So whenever I open the terminal, do I "see" the shell?

Can the kernel be seen on the screen or is it abstract and unseen?

sure you can see it, it is the file on the far right called vmlinuz in my attachment ;-)

When you open the terminal you are at the command line/CLI, shell etc.


The kernel is the core/brain of the OS

The kernel the low-level thing that makes everything work with your hardware. It's not something that you see with your eyes in your day to day work. Everything you see directly or indirectly depends on the kernel, but you only actually see the upper level stuff running.

And no, the command line is not the visual representation of the kernel.

I guess that if you can somehow actually "see" the (compiled) kernel, everything you will see is a bunch of ones and zeroes... unless you see its source files, which should have a more human-readable aspect (C code, if I'm not mistaken).

One possible interpretation of the question, is how do I know what the kernel is doing?

Well the kernel is always doing something, but you can see what the kernel sees fit to tell you by running


dmesg

in the terminal, which would give you the latest logs from the kernel. That is, what the kernel feels is important that you know. If you wanted to look at it more actively, you could run


watch 'dmesg|tail'

which would give you the same thing except it updates immediately whenever the kernel sends a new message to the log. It might not be terribly interesting though!

There's a Linux Kernel Map which gives a very general overview of its functionality:

Check out class shooting across the map there. It's like a bloody warzone in there.

I thought about installing the kernel once, but didn't think I would ever use it.

Nice use of popcorn while we are talking about the kernel. :)

Instead, only try to realize the truth: there is no kernel.
