nix3-realisation-info(1) General Commands Manual nix3-realisation-info(1) Warning This program is experimental <../../development/experimental- features.md#xp-feature-nix-command> and its interface is subject to change. Name nix realisation info - query information about one or several realisa- tions Synopsis nix realisation info [option...] installables... Description Display some information about the given realisation Examples Show some information about the realisation of the hello package: $ nix realisation info nixpkgs#hello --json [{"id":"sha256:3d382378a00588e064ee30be96dd0fa7e7df7cf3fbcace85a0e7b7dada1eef25!out","outPath":"fd3m7xawvrqcg98kgz5hc2vk3x9q0lh7-hello"}] Options • --json <#opt-json> Produce output in JSON format, suitable for consumption by another program. • --no-pretty <#opt-no-pretty> Print compact JSON output on a single line, even when the output is a terminal. Some commands may print multiple JSON objects on sepa- rate lines. See `--pretty`. • --pretty <#opt-pretty> Print multi-line, indented JSON output for readability. Default: indent if output is to a terminal. This option is only effective when `--json` is also specified. • --stdin <#opt-stdin> Read installables from the standard input. No default installable applied. Common evaluation options • --arg <#opt-arg> name expr Pass the value expr as the argument name to Nix functions. • --arg-from-file <#opt-arg-from-file> name path Pass the contents of file path as the argument name to Nix func- tions. • --arg-from-stdin <#opt-arg-from-stdin> name Pass the contents of stdin as the argument name to Nix functions. • --argstr <#opt-argstr> name string Pass the string string as the argument name to Nix functions. • --debugger <#opt-debugger> Start an interactive environment if evaluation fails. • --eval-store <#opt-eval-store> store-url The URL of the Nix store <../../store/types/index.md#store-url- format> to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them. • --impure <#opt-impure> Allow access to mutable paths and repositories. • --include <#opt-include> / -I path Add path to search path entries used to resolve lookup paths <../../language/constructs/lookup-path.md> This option may be given multiple times. Paths added through -I take precedence over the nix-path configura- tion setting <../../command-ref/conf-file.md#conf-nix-path> and the NIX_PATH environment variable <../../command-ref/env-common.md#env- NIX_PATH>. • --override-flake <#opt-override-flake> original-ref resolved-ref Override the flake registries, redirecting original-ref to resolved- ref. Common flake-related options • --commit-lock-file <#opt-commit-lock-file> Commit changes to the flake's lock file. • --inputs-from <#opt-inputs-from> flake-url Use the inputs of the specified flake as registry entries. • --no-registries <#opt-no-registries> Don't allow lookups in the flake registries. DEPRECATED Use --no-use-registries <../../command-ref/conf-file.md#conf- use-registries> instead. • --no-update-lock-file <#opt-no-update-lock-file> Do not allow any updates to the flake's lock file. • --no-write-lock-file <#opt-no-write-lock-file> Do not write the flake's newly generated lock file. • --output-lock-file <#opt-output-lock-file> flake-lock-path Write the given lock file instead of flake.lock within the top-level flake. • --override-input <#opt-override-input> input-path flake-url Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file. • --recreate-lock-file <#opt-recreate-lock-file> Recreate the flake's lock file from scratch. DEPRECATED Use nix flake update <../../command-ref/new-cli/nix3-flake- update.md> instead. • --reference-lock-file <#opt-reference-lock-file> flake-lock-path Read the given lock file instead of flake.lock within the top-level flake. • --update-input <#opt-update-input> input-path Update a specific flake input (ignoring its previous entry in the lock file). DEPRECATED Use nix flake update <../../command-ref/new-cli/nix3-flake- update.md> instead. Logging-related options • --debug <#opt-debug> Set the logging verbosity level to `debug'. • --log-format <#opt-log-format> format Set the format of log output; one of raw, internal-json, bar or bar- with-logs. • --print-build-logs <#opt-print-build-logs> / -L Print full build logs on standard error. • --quiet <#opt-quiet> Decrease the logging verbosity level. • --verbose <#opt-verbose> / -v Increase the logging verbosity level. Miscellaneous global options • --help <#opt-help> Show usage information. • --offline <#opt-offline> Disable substituters and consider all previously downloaded files up-to-date. • --option <#opt-option> name value Set the Nix configuration setting name to value (overriding nix.conf). • --refresh <#opt-refresh> Consider all previously downloaded files out-of-date. • --repair <#opt-repair> During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths. • --version <#opt-version> Show version information. Options that change the interpretation of installables • --all <#opt-all> Apply the operation to every store path. • --derivation <#opt-derivation> Operate on the store derivation <../../glossary.md#gloss-store- derivation> rather than its outputs. • --expr <#opt-expr> expr Interpret installables <../../command-ref/new- cli/nix.md#installables> as attribute paths relative to the Nix ex- pression expr. • --file <#opt-file> / -f file Interpret installables <../../command-ref/new- cli/nix.md#installables> as attribute paths relative to the Nix ex- pression stored in file. If file is the character -, then a Nix ex- pression is read from standard input. Implies --impure. • --recursive <#opt-recursive> / -r Apply operation to closure of the specified paths. Note See man nix.conf <../../command-ref/conf-file.md#command-line-flags> for overriding configuration settings with command line flags. nix3-realisation-info(1)
