# Examples
* Bundle Hello:
```console
# nix bundle nixpkgs#hello
# ./hello
Hello, world!
```
* Bundle a specific version of Nix:
```console
# nix bundle github:NixOS/nix/e3ddffb27e5fc37a209cfd843c6f7f6a9460a8ec
# ./nix --version
nix (Nix) 2.4pre20201215_e3ddffb
```
* Bundle a Hello using a specific bundler:
```console
# nix bundle --bundler github:NixOS/bundlers#toDockerImage nixpkgs#hello
# docker load < hello-2.10.tar.gz
# docker run hello-2.10:latest hello
Hello, world!
```
# Description
`nix bundle`, by default, packs the closure of the *installable* into a single
self-extracting executable. See the [`bundlers`
homepage](https://github.com/NixOS/bundlers) for more details.
> **Note**
>
> This command only works on Linux.
# Flake output attributes
If no flake output attribute is given, `nix bundle` tries the following
flake output attributes:
* `bundlers.<system>.default`
If an attribute *name* is given, `nix run` tries the following flake
output attributes:
* `bundlers.<system>.<name>`
# Bundlers
A bundler is specified by a flake output attribute named
`bundlers.<system>.<name>`. It looks like this:
```nix
bundlers.x86_64-linux = rec {
identity = drv: drv;
blender_2_79 = drv: self.packages.x86_64-linux.blender_2_79;
default = identity;
};
```
A bundler must be a function that accepts an arbitrary value (typically a
derivation or app definition) and returns a derivation.
