# Name `nix-store --add-fixed` - add paths to store using given hashing algorithm ## Synopsis `nix-store` `--add-fixed` [`--recursive`] *algorithm* *paths…* ## Description The operation `--add-fixed` adds the specified paths to the Nix store. Unlike `--add` paths are registered using the specified hashing algorithm, resulting in the same output path as a fixed-output derivation. This can be used for sources that are not available from a public url or broke since the download expression was written. This operation has the following options: - `--recursive`\ Use recursive instead of flat hashing mode, used when adding directories to the store. {{#include ./opt-common.md}} {{#include ../opt-common.md}} {{#include ../env-common.md}} ## Example ```console $ nix-store --add-fixed sha256 ./hello-2.10.tar.gz /nix/store/3x7dwzq014bblazs7kq20p9hyzz0qh8g-hello-2.10.tar.gz ```
