Escape the two dashes, otherwise they are combined into one long dash. I tested that this change is safe and still renders correctly on github and with the man pages. This commit also contains a small change to make it build locally. Assuming you have the dependencies installed you can do: ``` cd docs make html ``` Preview the html files in docs/build/html with `python -m http.server 8000 --directory build/html`.

## NAME
|
||
podman\-system\-prune - Remove all unused pod, container, image and volume data
|
||
|
||
## SYNOPSIS
|
||
**podman system prune** [*options*]
|
||
|
||
## DESCRIPTION
|
||
**podman system prune** removes all unused containers (both dangling and unreferenced), pods and optionally, volumes from local storage.
|
||
|
||
With the **\-\-all** option, you can delete all unused images. Unused images are dangling images as well as any image that does not have any containers based on it.
|
||
|
||
By default, volumes are not removed to prevent important data from being deleted if there is currently no container using the volume. Use the **\-\-volumes** flag when running the command to prune volumes as well.
|
||
|
||
## OPTIONS
|
||
#### **\-\-all**, **-a**
|
||
|
||
Recursively remove all unused pod, container, image and volume data (Maximum 50 iterations.)
|
||
|
||
#### **\-\-filter**=*filters*
|
||
|
||
Provide filter values.
|
||
|
||
The --filter flag format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")
|
||
|
||
Supported filters:
|
||
|
||
- `until` (_timestamp_) - only remove containers and images created before given timestamp
|
||
- `label` (label=_key_, label=_key=value_, label!=_key_, or label!=_key=value_) - only remove containers and images, 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 machine’s time.
|
||
|
||
The label filter accepts two formats. One is the label=... (label=_key_ or label=_key=value_), which removes containers and images with the specified labels. The other format is the label!=... (label!=_key_ or label!=_key=value_), which removes containers and images without the specified labels.
|
||
|
||
#### **\-\-force**, **-f**
|
||
|
||
Do not prompt for confirmation
|
||
|
||
#### **\-\-help**, **-h**
|
||
|
||
Print usage statement
|
||
|
||
#### **\-\-volumes**
|
||
|
||
Prune volumes currently unused by any container
