<Aside type="tip" title="Alias for --filter">

This flag is an alias for the [`--filter` flag](/docs/reference/cli/commands/run#filter).

When using this flag, the equivalent filter expression is used instead.

e.g.

```bash
terragrunt run --all --units-that-include shared.hcl -- plan
```

is equivalent to:

```bash
terragrunt run --all --filter 'reading=shared.hcl' -- plan
```
