R""( # Examples * Repair a store path, after determining that it is corrupt: ```console # nix store verify /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10 path '/nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10' was modified! expected hash 'sha256:1hd5vnh6xjk388gdk841vflicy8qv7qzj2hb7xlyh8lpb43j921l', got 'sha256:1a25lf78x5wi6pfkrxalf0n13kdaca0bqmjqnp7wfjza2qz5ssgl' # nix store repair /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10 ``` # Description This command attempts to "repair" the store paths specified by *installables* 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). )""
