Start an interactive shell based on a Nix expression. See also: tldr nix3 shell. More information: https://nixos.org/manual/nix/stable/command-ref/nix-shell.html.

• Start with nix expression in shell.nix or default.nix in the current directory:
  nix-shell
• Run shell command in non-interactive shell and exit:
  nix-shell --run "{{command}} {{argument1 argument2 ...}}"
• Start with expression in default.nix in the current directory:
  nix-shell {{default.nix}}
• Start with packages loaded from nixpkgs:
  nix-shell --packages {{package1 package2 ...}}
• Start with packages loaded from specific nixpkgs revision:
  nix-shell --packages {{package1 package2 ...}} -I nixpkgs={{https://github.com/NixOS/nixpkgs/archive/nixpkgs_revision.tar.gz}}
• Evaluate rest of file in specific interpreter, for use in #!-scripts (see https://nixos.org/manual/nix/stable/#use-as-a-interpreter):
  nix-shell -i {{interpreter}} --packages {{package1 package2 ...}}
