# Examples
|
||
|
|
|
||
|
|
* Verify the entire Nix store:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix store verify --all
|
||
|
|
```
|
||
|
|
|
||
|
|
* Check whether each path in the closure of Firefox has at least 2
|
||
|
|
signatures:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix store verify -r -n2 --no-contents $(type -p firefox)
|
||
|
|
```
|
||
|
|
|
||
|
|
* Verify a store path in the binary cache `https://cache.nixos.org/`:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix store verify --store https://cache.nixos.org/ \
|
||
|
|
/nix/store/v5sv61sszx301i0x6xysaqzla09nksnd-hello-2.10
|
||
|
|
```
|

# Description
|
||
|
|
|
||
|
|
This command verifies the integrity of the store paths *installables*,
|
||
|
|
or, if `--all` is given, the entire Nix store. For each path, it
|
||
|
|
checks that
|
||
|
|
|
||
|
|
* its contents match the NAR hash recorded in the Nix database; and
|
||
|
|
|
||
|
|
* it is *trusted*, that is, it is signed by at least one trusted
|
||
|
|
signing key, is content-addressed, or is built locally ("ultimately
|
||
|
|
trusted").
|

# Exit status
|
||
|
|
|
||
|
|
The exit status of this command is the sum of the following values:
|
||
|
|
|
||
|
|
* **1** if any path is corrupted (i.e. its contents don't match the
|
||
|
|
recorded NAR hash).
|
||
|
|
|
||
|
|
* **2** if any path is untrusted.
|
||
|
|
|
||
|
|
* **4** if any path couldn't be verified for any other reason (such as
|
||
|
|
an I/O error).
