# compact
This command allows us to filters out rows with empty columns. Other commands are capable of feeding `compact` with their output through pipelines.
## Usage

```shell
> [input-command] | compact [column-name]
```
## Examples

Let's say we have a table like this:
```shell
> open contacts.json
━━━┯━━━━━━━━━━┯━━━━━━━━━━━━━━━━━━
# │ name │ email
───┼──────────┼──────────────────
0 │ paul │ paul@example.com
1 │ andres │
2 │ jonathan │
━━━┷━━━━━━━━━━┷━━━━━━━━━━━━━━━━━━
```
`compact` allows us to filter out rows with empty `email` column:
```shell
> open contacts.json | compact email
━━━━━━┯━━━━━━━━━━━━━━━━━━
name │ email
──────┼──────────────────
paul │ paul@example.com
━━━━━━┷━━━━━━━━━━━━━━━━━━
```
