Name

       nix-store --import - import Nix Archive into the store

Synopsis

       nix-store --import

Description

       The  operation  --import  reads  a serialisation of a set of store objects produced by nix-store --export
       from standard input, and adds those store objects to the specified Nix store.  Paths that  already  exist
       in  the  target Nix store are ignored.  If a path refers to another path that doesn’t exist in the target
       Nix store, the import fails.

              Note

              For efficient transfer of closures to remote machines over SSH, use nix-copy-closure.

Examples

              Example

              Given a closure of GNU Hello as a file:

              $ storePath="$(nix-build '<nixpkgs>' -I nixpkgs=channel:nixpkgs-unstable -A hello --no-out-link)"
              $ nix-store --export $(nix-store --query --requisites $storePath) > hello.closure

              Import the closure into a remote SSH store using the --store option:

              $ nix-store --import --store ssh://alice@itchy.example.org < hello.closure

                                                                                           nix-store --import(1)
