# network prune
```markdown
Usage: docker network prune [OPTIONS]
Remove all unused networks
Options:
--filter filter Provide filter values (e.g. 'until=<timestamp>')
-f, --force Do not prompt for confirmation
--help Print usage
```
Remove all unused networks. Unused networks are those which are not referenced by any containers.
Example output:
```bash
$ docker network prune
WARNING! This will remove all networks not used by at least one container.
Are you sure you want to continue? [y/N] y
Deleted Networks:
n1
n2
```
## 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:
* until (`<timestamp>`) - only remove networks created before given timestamp
The `until` filter can be Unix timestamps, date formatted
timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
relative to the daemon machines 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 following removes networks created more than 5 minutes ago. Note that
system networks such as `bridge`, `host`, and `none` will never be pruned:
```bash
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
7430df902d7a bridge bridge local
ea92373fd499 foo-1-day-ago bridge local
ab53663ed3c7 foo-1-min-ago bridge local
97b91972bc3b host host local
f949d337b1f5 none null local
$ docker network prune --force --filter until=5m
Deleted Networks:
foo-1-day-ago
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
7430df902d7a bridge bridge local
ab53663ed3c7 foo-1-min-ago bridge local
97b91972bc3b host host local
f949d337b1f5 none null local
```
