In addition: - Take the opportunity to add a bunch more missing hyperlinks, too. - Remove some glossary entries that are now subsumed by dedicated pages. We used to not be able to do this without breaking link fragments, but now we can, so pick up where we left off. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>

Examples
-
Show the store derivation that results from evaluating the Hello package:
# nix derivation show nixpkgs#hello { "/nix/store/s6rn4jz1sin56rf4qj5b5v8jxjm32hlk-hello-2.10.drv": { … } } -
Show the full derivation graph (if available) that produced your NixOS system:
# nix derivation show -r /run/current-system -
Print all files fetched using
fetchurlby Firefox's dependency graph:# nix derivation show -r nixpkgs#firefox \ | jq -r '.[] | select(.outputs.out.hash and .env.urls) | .env.urls' \ | uniq | sortNote that
.outputs.out.hashselects fixed-output derivations (derivations that produce output with a specified content hash), while.env.urlsselects derivations with aurlsattribute.
Description
This command prints on standard output a JSON representation of the store derivations to which installables evaluate.
Store derivations are used internally by Nix. They are store paths with
extension .drv that represent the build-time dependency graph to which
a Nix expression evaluates.
By default, this command only shows top-level derivations, but with
--recursive, it also shows their dependencies.
nix derivation show outputs a JSON map of store paths to derivations in the following format:
{{#include ../../protocols/json/derivation.md}}
