nix store copy-sigs

nix store copy-sigs [option…] installables…

• --substituter / -s store-uri
  Copy signatures from the specified store.

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