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

nix store add [option…] path

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.

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

•
--hash-algo hash-algo
Hash algorithm (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
