}
I know that the "layer" architecture of any *nix OS is kernel-shell-utility ("inner to outer").
if we installed say Debian-Server and got some CLI utilities with it,
Should all these utilities work the same with all shells (Bash, Dash, Korn, etc)?
In other words, are Linux utilities (which I assume are kernel-dependent) also shell-dependent?

You get no problem invoking them from perl or python, why should there be a problem running them from a different shell?

I know that the "layer" architecture of any *nix OS is kernel-shell-utility ("inner to outer").
It isn’t. Everything runs on top of the kernel, and “utilities” which aren’t shell scripts don’t need a shell, and are therefore not dependent on a specific shell.
Some programs do need others, for example a Wayland client needs a Wayland compositor. But there’s no general layering involving shells.
