Print the store path produced by
nixpkgs#hello
:# nix path-info nixpkgs#hello /nix/store/v5sv61sszx301i0x6xysaqzla09nksnd-hello-2.10
-
Show the closure sizes of every path in the current NixOS system closure, sorted by size:
# nix path-info -rS /run/current-system | sort -nk2 /nix/store/hl5xwp9kdrd1zkm0idm3kkby9q66z404-empty 96 /nix/store/27324qvqhnxj3rncazmxc4mwy79kz8ha-nameservers 112 … /nix/store/539jkw9a8dyry7clcv60gk6na816j7y8-etc 5783255504 /nix/store/zqamz3cz4dbzfihki2mk7a63mbkxz9xq-nixos-system-machine-20.09.20201112.3090c65 5887562256
-
Show a package's closure size and all its dependencies with human readable sizes:
# nix path-info -rsSh nixpkgs#rustc /nix/store/01rrgsg5zk3cds0xgdsq40zpk6g51dz9-ncurses-6.2-dev 386.7K 69.1M /nix/store/0q783wnvixpqz6dxjp16nw296avgczam-libpfm-4.11.0 5.9M 37.4M …
-
Check the existence of a path in a binary cache:
# nix path-info -r /nix/store/blzxgyvrk32ki6xga10phr4sby2xf25q-geeqie-1.5.1 --store https://cache.nixos.org/ path '/nix/store/blzxgyvrk32ki6xga10phr4sby2xf25q-geeqie-1.5.1' is not valid
-
Print the 10 most recently added paths (using --json and the jq(1) command):
# nix path-info --json --all | jq -r 'sort_by(.registrationTime)[-11:-1][].path'
-
Show the size of the entire Nix store:
# nix path-info --json --all | jq 'map(.narSize) | add' 49812020936
-
Show every path whose closure is bigger than 1 GB, sorted by closure size:
# nix path-info --json --all -S \ | jq 'map(select(.closureSize > 1e9)) | sort_by(.closureSize) | map([.path, .closureSize])' [ …, [ "/nix/store/zqamz3cz4dbzfihki2mk7a63mbkxz9xq-nixos-system-machine-20.09.20201112.3090c65", 5887562256 ] ]
-
Print the path of the store derivation produced by
nixpkgs#hello
:# nix path-info --derivation nixpkgs#hello /nix/store/s6rn4jz1sin56rf4qj5b5v8jxjm32hlk-hello-2.10.drv
# Description
This command shows information about the store paths produced by
*installables*, or about all paths in the store if you pass `--all`.
By default, this command only prints the store paths. You can get
additional information by passing flags such as `--closure-size`,
--size`, `--sigs` or `--json`.
> **Warning**
>
> Note that `nix path-info` does not build or substitute the
> *installables* you specify. Thus, if the corresponding store paths
> don't already exist, this command will fail. You can use `nix build`
> to ensure that they exist.
