`nix store optimise`

- Delete a specific store path (most be unused):

`nix store delete /nix/store/{{checksum-package-version.ext}}`

- List a contents of the store path, on a remote store:

`nix store --store {{https://cache.nixos.org}} ls /nix/store/{{checksum-package-version.ext}}`

- Show the differences in versions between two store paths, with their respective dependencies:

`nix store diff-closures /nix/store/{{checksum-package-version.ext}} /nix/store/{{checksum-package-version.ext}}`
