The following types of installable are supported by most commands:
- [Flake output attribute](#flake-output-attribute) (experimental)
- This is the default
- [Store path](#store-path)
- This is assumed if the argument is a Nix store path or a symlink to a Nix store path
- [Nix file](#nix-file), optionally qualified by an attribute path
- Specified with `--file`/`-f`
- [Nix expression](#nix-expression), optionally qualified by an attribute path
- Specified with `--expr`/`-E`
For most commands, if no installable is specified, `.` is assumed.
That is, Nix will operate on the default flake output attribute of the flake in the current directory.
