## Filtering
The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
The currently supported filters are:
* enabled (boolean - true or false, 0 or 1)
* capability (string - currently `volumedriver`, `networkdriver`, `ipamdriver`, or `authz`)
### enabled
The `enabled` filter matches on plugins enabled or disabled.
### capability
The `capability` filter matches on plugin capabilities. One plugin
might have multiple capabilities. Currently `volumedriver`, `networkdriver`,
`ipamdriver`, and `authz` are supported capabilities.
```bash
$ docker plugin install --disable tiborvass/no-remove

$ docker plugin ls --filter enabled=true
