Name¶
nix store optimise - replace identical files in the store by hard links
Synopsis¶
nix store optimise [option…]
Examples¶
- •
- Optimise the Nix store:
nix store optimise
Description¶
This command deduplicates the Nix store: it scans the store for regular files with identical contents, and replaces them with hard links to a single instance.
Note that you can also set auto-optimise-store to true in nix.conf to perform this optimisation incrementally whenever a new path is added to the Nix store. To make this efficient, Nix maintains a content-addressed index of all the files in the Nix store in the directory /nix/store/.links/.
