```
or the long version: `nix-env --install --file default.nix`.

You can get the out path by running `nix-store -q --outputs $(nix-instantiate default.nix)` or `nix eval '("${import ./default.nix}")'` before installation, or `nix-env -q --out-path --no-name hello` after installing.
To see the contents of the .drv file, run: `nix show-derivation $(nix-instantiate default.nix)` or `nix show-derivation $(nix-store -q --deriver $(nix eval '("${import ./default.nix}")' | cut -d '"' -f 1))`.
