# `mix nerves.artifact.purge`
[🔗](https://github.com/nerves-project/nerves/blob/v2.0.0-pre.2/lib/mix/tasks/nerves.artifact.purge.ex#L5)

Delete Nerves artifact files and container build volumes

By default, deletes only the artifacts matching the current fingerprint of
the specified package. Pass `--all` to every build of the artifact.

Shows what will be deleted and asks for confirmation before proceeding.

`MIX_TARGET` must be set so that target-specific dependencies are
available. When no package name is given, the task auto-selects if
there is exactly one Nerves artifact dependency.

## Command line options

  * `--all` - Delete all versions, not just the current one
  * `--yes` - Skip the confirmation prompt

## Examples

    $ MIX_TARGET=rpi0 mix nerves.artifact.purge
    $ MIX_TARGET=rpi0 mix nerves.artifact.purge test_system_rpi0
    $ MIX_TARGET=rpi0 mix nerves.artifact.purge --all test_system_rpi0
    $ MIX_TARGET=rpi0 mix nerves.artifact.purge --yes test_system_rpi0
