nix store sign

Common evaluation options

• --arg name expr

Pass the value expr as the argument name to Nix functions.

• --arg-from-file name path

Pass the contents of file path as the argument name to Nix functions.

• --arg-from-stdin name

Pass the contents of stdin as the argument name to Nix functions.

• --argstr name string

Pass the string string as the argument name to Nix functions.

• --debugger

Start an interactive environment if evaluation fails.

• --eval-store store-url

The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.

• --impure

Allow access to mutable paths and repositories.

• --include / -I path

Add path to search path entries used to resolve lookup paths

This option may be given multiple times.

Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.

• --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.

• --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.

• --output-lock-file flake-lock-path

Write the given lock file instead of flake.lock within the top-level flake.

• --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.

• --reference-lock-file flake-lock-path

Read the given lock file instead of flake.lock within the top-level flake.

• --update-input input-path

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

Logging-related options

• --debug

Set the logging verbosity level to ‘debug’.

• --log-format format

Set the format of log output; one of raw, internal-json, bar or bar-with-logs.

• --print-build-logs / -L

Print full build logs on standard error.

• --quiet

Decrease the logging verbosity level.

• --verbose / -v

Increase the logging verbosity level.

Miscellaneous global options

• --help

Show usage information.

• --offline

Disable substituters and consider all previously downloaded files up-to-date.

• --option name value

Set the Nix configuration setting name to value (overriding nix.conf).

• --refresh

Consider all previously downloaded files out-of-date.

• --repair

During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.

• --version

Show version information.

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. Implies --impure.

• --recursive / -r

Apply operation to closure of the specified paths.
