These are paths inside the Nix store, or symlinks that resolve to a path in the Nix store.
-### Store derivation
+A [store derivation] is also addressed by store path.
Example: `/nix/store/p7gp6lxdg32h4ka1q398wd9r2zkbbz2v-hello-2.10.drv`
-By default, if you pass a [store derivation] path to a `nix` subcommand other than [`show-derivation`](./nix3-show-derivation.md), the command will operate on the [output path]s of the derivation.
+If you want to refer to an output path of that store derivation, add the output name preceded by a caret (`^`).
-[output path]: ../../glossary.md#gloss-output-path
+Example: `/nix/store/p7gp6lxdg32h4ka1q398wd9r2zkbbz2v-hello-2.10.drv^out`
-For example, [`nix path-info`](./nix3-path-info.md) prints information about the output paths:
+All outputs can be referred to at once with the special syntax `^*`.
-```console
-# nix path-info --json /nix/store/p7gp6lxdg32h4ka1q398wd9r2zkbbz2v-hello-2.10.drv
-[{"path":"/nix/store/v5sv61sszx301i0x6xysaqzla09nksnd-hello-2.10",…}]

-If you want to operate on the store derivation itself, pass the `--derivation` flag.
