If you want portable shell-scripts that come with their dependencies bundled, Nix also has a solution: writeShellApplication[0] (and more simpler ones like writeShellScript).

    writeShellApplication {
      name = "show-nixos-org";

      runtimeInputs = [ curl w3m ];

      text = ''
        curl -s 'https://nixos.org' | w3m -dump -T text/html
      '';
    }

writeShellApplication will call shellcheck[1] on your script and fail to build if there are any issues reported, which I think is the only sane default.
