nix store dump-path - serialise a store path to stdout in NAR format
nix store dump-path [option...] installables...
To get a NAR containing the GNU Hello package:
# nix store dump-path nixpkgs#hello > hello.nar
To get a NAR from the binary cache https://cache.nixos.org/:
# nix store dump-path --store https://cache.nixos.org/ \ /nix/store/7crrmih8c52r8fbnqb933dxrsp44md93-glibc-2.25 > glibc.nar
This command generates a NAR file containing the serialisation of the store path installable. The NAR is written to standard output.
Common evaluation options:
Pass the value expr as the argument name to Nix functions.
Pass the string string as the argument name to Nix functions.
The Nix store to use for evaluations.
Allow access to mutable paths and repositories.
Add path to the list of locations used to look up
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options:
Commit changes to the flake's lock file.
Use the inputs of the specified flake as registry entries.
Don't allow lookups in the flake registries. This option is deprecated; use
Do not allow any updates to the flake's lock file.
Do not write the flake's newly generated lock file.
Override a specific flake input (e.g.
dwarffs/nixpkgs). This implies
Recreate the flake's lock file from scratch.
Update a specific flake input (ignoring its previous entry in the lock file).
Options that change the interpretation of installables:
Apply the operation to every store path.
Operate on the store derivation rather than its outputs.
Interpret installables as attribute paths relative to the Nix expression expr.
Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input.
Apply operation to closure of the specified paths.
