output vs "inside" of a build

so I'm installing a c compiler and a library, but these are not final
products.  how to have them as final?

e.g. I want to have that arm compiler and C library in my environment.
how to use that .nix file to set up a nix shell?

So basically, nix-build, nix-shell and nix-env can be used with the
.nix file.

nix-build and nix-env expose only the end results
while nix-shell has all the dependencies available.

to remove a profile from nix-env:

$ nix-env --list-generations
