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.

{{#include ./opt-common.md}}

{{#include ../opt-common.md}}

{{#include ../env-common.md}}

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
