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/.

Options

Logging-related options

--debug Set the logging verbosity level to ‘debug'.
--log-format format Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
--print-build-logs / -L Print full build logs on standard error.
--quiet Decrease the logging verbosity level.
