nix3-store-add(1)

Add a file or directory to the Nix store

Warning
This program is experimental ⟨@docroot@/development/experimental-features.md#xp-feature-nix-command⟩ and its interface is subject to change.

Name

nix store add - Add a file or directory to the Nix store

Synopsis

nix store add [option…] path

Description

Copy path to the Nix store, and print the resulting store path on standard output.

Warning

The resulting store path is not registered as a garbage collector root, so it could be deleted before you have a chance to register it.

Examples

Add a directory to the store:

# mkdir dir
# echo foo > dir/bar
# nix store add ./dir
/nix/store/6pmjx56pm94n66n4qw1nff0y1crm8nqg-dir
# cat /nix/store/6pmjx56pm94n66n4qw1nff0y1crm8nqg-dir/bar
foo

Options

•: --dry-run ⟨#opt-dry-run⟩

: Show what this command would do without doing it.

•: --hash-algo ⟨#opt-hash-algo⟩ hash-algo

: Hash algorithm (md5, sha1, sha256, or sha512).

•: --mode ⟨#opt-mode⟩ content-address-method

How to compute the content-address of the store object. One of:

•: nar ⟨@docroot@/store/store-object/content-address.md#method-nix-archive⟩ (the default): Serialises the input as a Nix Archive ⟨@docroot@/store/file-system-object/content-address.md#serial-nix-archive⟩ and passes that to the hash function.

•: flat ⟨@docroot@/store/store-object/content-address.md#method-flat⟩\c : Assumes that the input is a single file and directly passes ⟨@docroot@/store/file-system-object/content-address.md#serial-flat⟩ it to the hash function.

•: text ⟨@docroot@/store/store-object/content-address.md#method-text⟩\c : Like flat, but used for derivations ⟨@docroot@/glossary.md#store-derivation⟩ serialized in store object and builtins.toFile ⟨@docroot@/language/builtins.html#builtins-toFile⟩\c . For advanced use-cases only; for regular usage prefer nar and flat.

•: --name ⟨#opt-name⟩ / -n name

: Override the name component of the store path. It defaults to the base name of path.

Logging-related options

•: --debug ⟨#opt-debug⟩

: Set the logging verbosity level to ‘debug’.

•: --log-format ⟨#opt-log-format⟩ format

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

•: --print-build-logs ⟨#opt-print-build-logs⟩ / -L

: Print full build logs on standard error.

•: --quiet ⟨#opt-quiet⟩

: Decrease the logging verbosity level.

•: --verbose ⟨#opt-verbose⟩ / -v

: Increase the logging verbosity level.

Miscellaneous global options

•: --help ⟨#opt-help⟩

: Show usage information.

•: --offline ⟨#opt-offline⟩

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

•: --option ⟨#opt-option⟩ name value

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

•: --refresh ⟨#opt-refresh⟩

: Consider all previously downloaded files out-of-date.

•: --version ⟨#opt-version⟩

: Show version information.

Note

See man nix.conf ⟨@docroot@/command-ref/conf-file.md#command-line-flags⟩ for overriding configuration settings with command line flags.
