# where

This command filters the content of a table based on a condition passed as a parameter, which must be a boolean expression making use of any of the table columns. Other commands such as `ls` are capable of feeding `where` with their output through pipelines.

## Usage
```shell
> [input-command] | where [condition]
```

## Examples 

```shell
> ls | where size > 4kb
