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).
