nix3-store-add - Man Page

Add a file or directory to the Nix store

Warning
This program is experimental and its interface is subject to change.

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
Show what this command would do without doing it.
--hash-algo hash-algo
Hash algorithm (blake3, md5, sha1, sha256, or sha512).
--mode content-address-method
How to compute the content-address of the store object. One of:
- nar (the default): Serialises the input as a Nix Archive and passes that to the hash function.
- flat : Assumes that the input is a single file and directly passes it to the hash function.
- text : Like flat, but used for derivations serialized in store object and builtins.toFile . For advanced use-cases only; for regular usage prefer nar and flat.
--name / -n name
Override the name component of the store path. It defaults to the base name of path.

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

--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
