# 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 ━━━━━━┷━━━━━━━━━━━━━━━━━━ ```
