nix3-store-optimise(1) General Commands Manual nix3-store-optimise(1) Warning This program is experimental and its interface is subject to change. Name nix store optimise - replace identical files in the store by hard links Synopsis nix store optimise [option] Examples o 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/. Options Logging-related options o --debug Set the logging verbosity level to `debug'. o --log-format format Set the format of log output; one of raw, internal-json, bar or bar-with-logs. o --print-build-logs / -L Print full build logs on standard error. o --quiet Decrease the logging verbosity level. o --verbose / -v Increase the logging verbosity level. Miscellaneous global options o --help Show usage information. o --offline Disable substituters and consider all previously downloaded files up-to-date. o --option name value Set the Nix configuration setting name to value (overriding nix.conf). o --refresh Consider all previously downloaded files out-of-date. o --version Show version information. Note See man nix.conf for overriding configuration settings with command line flags. nix3-store-optimise(1)
