#### Preview Changes

You can preview the changes without applying the changes with `jack diff`.

```sh
jack diff hi-web-stag
```

You should see something similar to this:

<img src="/img/tutorials/jack-diff.png" class="doc-photo" />

By default, `jack diff` cleans up after itself and removes the originally downloaded `.elasticbeanstalk/saved_configs`.  If you would like to keep that file around for further inspection, use the `--dirty` flag.

```sh
jack diff hi-web-stag --dirty
```
