      nix path-info shows information about store paths, replacing nix-store -q. A useful feature is the option --closure-size (-S). For example, the following command show the closure sizes of every path in the current NixOS system closure, sorted by size: nix path-info -rS /run/current-system | sort -nk2

      The Nixpkgs pull request template has a checkbox "Determined the impact on package closure size (by running nix path-info -S before and after)" but there is only 4 instances of path-info in the Nix manual (and none in the Nixpkgs manual).

      nix --help says

      path-info        query information about store paths

      so the command works at the bottom but what switches are available for example? From the examples, -r and -S is valid but where are they documented?

      nix path-info -rS $(readlink -f $(which vim))

      nix TODO path-info
