### <a name="filter"></a> Filtering (--filter)

The filtering flag (`--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:

* until (`<timestamp>`) - only remove containers created before given timestamp
* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove containers with (or without, in case `label!=...` is used) the specified labels.

The `until` filter can be Unix timestamps, date formatted
timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
relative to the daemon machine’s time. Supported formats for date
formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
timezone on the daemon will be used if you do not provide either a `Z` or a
`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
fraction of a second no more than nine digits long.

The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
which removes containers with the specified labels. The other
format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
containers without the specified labels.

The following removes containers created more than 5 minutes ago:

```console
$ docker ps -a --format 'table {{.ID}}\t{{.Image}}\t{{.Command}}\t{{.CreatedAt}}\t{{.Status}}'
