Hi everyone, I'm new to nix and I'm wondering if I could make a derivation that creates a link: `ln -s ${pkgs.bash}/bin/bash /bin/bash` to allow all the scripts in a  project I have to work. All the scripts have a hardcoded `#!/bin/bash` as the interpreter.

I've read this: https://nixos.org/nix/manual/#ssec-derivation looking for something that might do what I want.

I've tried this:
```
➜ cat shell.nix
with import <nixpkgs> {};

stdenv.mkDerivation {
    name = "node";
    buildInputs = [
      nodejs
      jq
    ];
    shellHook = ''
        export PATH="$PWD/node_modules/.bin/:$PATH"
        ln -s ${pkgs.bash}/bin/bash /bin/bash
    '';
}
```

Any links or google keywords that will point me in the right direction?
