Name

nix store delete - delete paths from the Nix store

Synopsis

nix store delete [/option/…] installables…

Examples

Delete a specific store path:

# nix store delete /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10

Description

This command deletes the store paths specified by installables, but only if it is safe to do so; that is, when the path is not reachable from a root of the garbage collector. This means that you can only delete paths that would also be deleted by nix store gc. Thus, nix store delete is a more targeted version of nix store gc.

With the option --ignore-liveness, reachability from the roots is ignored. However, the path still won't be deleted if there are other paths in the store that refer to it (i.e., depend on it).

Options

--ignore-liveness Do not check whether the paths are reachable from a root.
--stdin Read installables from the standard input. No default installable applied.

Common evaluation options

--arg name expr Pass the value expr as the argument name to Nix functions.
--arg-from-file name path Pass the contents of file path as the argument name to Nix functions.
--arg-from-stdin name Pass the contents of stdin as the argument name to Nix functions.
--argstr name string Pass the string string as the argument name to Nix functions.
--debugger Start an interactive environment if evaluation fails.
--eval-store store-url The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
--impure Allow access to mutable paths and repositories.
--include / -I path Add path to search path entries used to resolve lookup paths This option may be given multiple times. Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.
--override-flake original-ref resolved-ref Override the flake registries, redirecting original-ref to resolved-ref.

Common flake-related options

--commit-lock-file Commit changes to the flake's lock file.
--inputs-from flake-url Use the inputs of the specified flake as registry entries.
--no-registries

Don't allow lookups in the flake registries.

DEPRECATED

Use --no-use-registries instead.
--no-update-lock-file Do not allow any updates to the flake's lock file.
--no-write-lock-file Do not write the flake's newly generated lock file.
--output-lock-file flake-lock-path Write the given lock file instead of flake.lock within the top-level flake.
--override-input input-path flake-url Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file.
--recreate-lock-file

Recreate the flake's lock file from scratch.

DEPRECATED

Use nix flake update instead.
--reference-lock-file flake-lock-path Read the given lock file instead of flake.lock within the top-level flake.
--update-input input-path

Update a specific flake input (ignoring its previous entry in the lock file).

DEPRECATED

Use nix flake update instead.

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.
--repair During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
--version Show version information.

Options that change the interpretation of installables

--all Apply the operation to every store path.
--derivation Operate on the store derivation rather than its outputs.
--expr expr Interpret installables as attribute paths relative to the Nix expression expr.
--file / -f file Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input. Implies --impure.
--recursive / -r Apply operation to closure of the specified paths. Note See man nix.conf for overriding configuration settings with command line flags.
