+
+# Description
+
+This command recreates the lock file of a flake (`flake.lock`), thus
+updating the lock for every mutable input (like `nixpkgs`) to its
+current version. This is equivalent to passing `--recreate-lock-file`
+to any command that operates on a flake. That is,
+
+```console
+# nix flake update
+# nix build
+```
+
+is equivalent to:
+
+```console
+# nix build --recreate-lock-file
+```
