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/.
