Name

       nix store dump-path - serialise a store path to stdout in NAR format

Synopsis

       nix store dump-path [option…] installables…

Examples

       • 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

Description

       This  command  generates  a  NAR  file  containing  the  serialisation  of  the store path
       installable. The NAR is written to standard output.

Options

       Common evaluation options:

       • --arg name expr
         Pass the value expr as the argument name to Nix functions.

       • --argstr name string
         Pass the string string as the argument name to Nix functions.

       • --eval-store store-url
         The Nix store to use for evaluations.

       • --impure
         Allow access to mutable paths and repositories.

       • --include / -I path
         Add path to the list of locations used to look up <...> file names.

       • --override-flake original-ref resolved-ref
         Override the flake registries, redirecting original-ref to resolved-ref.

       Common flake-related options:

       • --commit-lock-file
         Commit changes to the flake’s lock file.

       • --inputs-from flake-url
         Use the inputs of the specified flake as registry entries.

       • --no-registries
         Don’t allow lookups in the flake registries. This option is  deprecated;  use  --no-use-
         registries.

       • --no-update-lock-file
         Do not allow any updates to the flake’s lock file.

       • --no-write-lock-file
         Do not write the flake’s newly generated lock file.

       • --override-input input-path flake-url
         Override  a  specific  flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-
         file.

       • --recreate-lock-file
         Recreate the flake’s lock file from scratch.

       • --update-input input-path
         Update a specific flake input (ignoring its previous entry in the lock file).

       Options that change the interpretation of installables:

       • --all
         Apply the operation to every store path.

       • --derivation
         Operate on the store derivation rather than its outputs.

       • --expr expr
         Interpret installables as attribute paths relative to the Nix expression expr.

       • --file / -f file
         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.

       • --recursive / -r
         Apply operation to closure of the specified paths.

                                                                          nix3-store-dump-path(1)
