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
     *	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  sin-
     gle instance.

     Note  that you can also set auto-optimise-store to true in nix.conf to per-
     form 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.

     *	--verbose / -v

	Increase the logging verbosity level.

   Miscellaneous global options
     *	--help

	Show usage information.

     *	--offline

	Disable substituters and consider all previously downloaded files up-to-
	date.

     *	--option name value

	Set the Nix configuration setting name to value (overriding nix.conf).

     *	--refresh

	Consider all previously downloaded files out-of-date.

     *	--version

	Show version information.

	Note

	See man nix.conf for overriding configuration settings with command line
	flags.
