nix-store -repair-path(1)   General Commands Manual  nix-store -repair-path(1)

Name
       nix --repair-path - re-download path from substituter

Synopsis
       nix-store --repair-path paths<?>

Description
       The operation --repair-path attempts to "repair" the specified paths by
       redownloading them using the available substituters. If no substitutes
       are available, then repair is not possible.

              Warning

              During repair, there is a very small time window during which
              the old path (if it exists) is moved out of the way and replaced
              with the new path. If repair is interrupted in between, then the
              system may be left in a broken state (e.g., if the path contains
              a critical system component like the GNU C Library).

Example
       $ nix-store --verify-path /nix/store/dj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13
