# Copying Closures via SSH
|
|
||||||
|
|
||||||
The command `nix-copy-closure` copies a Nix store path along with all
|
|
||||||
its dependencies to or from another machine via the SSH protocol. It
|
|
||||||
doesn’t copy store paths that are already present on the target machine.
|
|
||||||
For example, the following command copies Firefox with all its
|
|
||||||
dependencies:
|
|
||||||
|
|
||||||
$ nix-copy-closure --to alice@itchy.example.org $(type -p firefox)
|
|
||||||
|
|
||||||
See the [manpage for `nix-copy-closure`](../command-ref/nix-copy-closure.md) for details.
|
|
||||||
|
|
||||||
With `nix-store
|
|
||||||
--export` and `nix-store --import` you can write the closure of a store
|
|
||||||
path (that is, the path and all its dependencies) to a file, and then
|
|
||||||
unpack that file into another Nix store. For example,
|
|
||||||
|
|
||||||
$ nix-store --export $(nix-store --query --requisites $(type -p firefox)) > firefox.closure
|
|
||||||
|
|
||||||
writes the closure of Firefox to a file. You can then copy this file to
|
|
||||||
another machine and install the closure:
|
|
||||||
|
|
||||||
$ nix-store --import < firefox.closure
|
|
||||||
|
|
||||||
Any store paths in the closure that are already present in the target
|
|
||||||
store are ignored. It is also possible to pipe the export into another
|
|
||||||
command, e.g. to copy and install a closure directly to/on another
|
|
||||||
machine:
|
|
||||||
|
|
||||||
$ nix-store --export $(nix-store --query --requisites $(type -p firefox)) | bzip2 | \
|
|
||||||
ssh alice@itchy.example.org "bunzip2 | nix-store --import"
|
|
||||||
|
|
||||||
However, `nix-copy-closure` is generally more efficient because it only
|
|
||||||
copies paths that are not already present in the target Nix store.
