Name
nix realisation info - query information about one or several realisations
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
Produce output in JSON format, suitable for consumption by another program.
Common evaluation options:
-
--argname expr
Pass the value expr as the argument name to Nix functions. -
--argstrname string
Pass the string string as the argument name to Nix functions. -
--eval-storestore-url
The Nix store to use for evaluations. -
--impure
Allow access to mutable paths and repositories. -
--include/-Ipath
Add path to the list of locations used to look up<...>file names. -
--override-flakeoriginal-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-fromflake-url
Use the inputs of the specified flake as registry entries. -
--no-registries
Don't allow lookups in the flake registries. This option is deprecated; use--no-use-registries. -
--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. -
--override-inputinput-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. -
--update-inputinput-path
Update a specific flake input (ignoring its previous entry in the lock file).
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. -
--exprexpr
Interpret installables as attribute paths relative to the Nix expression expr. -
--file/-ffile
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. -
--recursive/-r
Apply operation to closure of the specified paths.
