# default
|
||
|
|
|
||
|
|
This command sets a default row's column if missing. Other commands are capable of feeding `default` with their output through pipelines.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
```shell
|
||
|
|
> [input-command] | default [column-name] [column-value]
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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 │
|
||
|
|
━━━┷━━━━━━━━━━┷━━━━━━━━━━━━━━━━━━
|
||
|
|
```
|
||
|
|
|
||
|
|
`default` allows us to fill `email` column with a default value:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
> open contacts.json | default email "no-reply@example.com"
|
||
|
|
━━━┯━━━━━━━━━━┯━━━━━━━━━━━━━━━━━━━━━━
|
||
|
|
# │ name │ email
|
||
|
|
───┼──────────┼──────────────────────
|
||
|
|
0 │ paul │ paul@example.com
|
||
|
|
1 │ andres │ no-reply@example.com
|
||
|
|
2 │ jonathan │ no-reply@example.com
|
||
|
|
━━━┷━━━━━━━━━━┷━━━━━━━━━━━━━━━━━━━━━━
|
||
|
|
```
