# Name
|
|||
|
|
|
|||
|
|
`nix-store --export` - export store paths to a Nix Archive
|
|||
|
|
|
|||
|
|
## Synopsis
|
|||
|
|
|
|||
|
|
`nix-store` `--export` *paths…*
|
|||
|
|
|
|||
|
|
## Description
|
|||
|
|
|
|||
|
|
The operation `--export` writes a serialisation of the specified store
|
|||
|
|
paths to standard output in a format that can be imported into another
|
|||
|
|
Nix store with `nix-store --import`. This is like `nix-store
|
|||
|
|
--dump`, except that the NAR archive produced by that command doesn’t
|
|||
|
|
contain the necessary meta-information to allow it to be imported into
|
|||
|
|
another Nix store (namely, the set of references of the path).
|
|||
|
|
|
|||
|
|
This command does not produce a *closure* of the specified paths, so if
|
|||
|
|
a store path references other store paths that are missing in the target
|
|||
|
|
Nix store, the import will fail.

|||

|
{{#include ./opt-common.md}}
|
|||
|
|
|
|||
|
|
{{#include ../opt-common.md}}
|
|||
|
|
|
|||
|
|
{{#include ../env-common.md}}
|
|||
|
|
|
|||
|
|
# Examples
|
|||
|
|
|
|||
|
|
To copy a whole closure, do something
|
|||
|
|
like:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
$ nix-store --export $(nix-store -qR paths) > out
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
To import the whole closure again, run:
|
|||
|
|
|
|||
|
|
```console
|
|||
|
|
$ nix-store --import < out
|
|||
|
|
```
