NAME
podman-system-df - Show podman disk usage
SYNOPSIS
podman system df [options]
DESCRIPTION
Show podman disk usage for images, containers and volumes.
Note: The RECLAIMABLE size that is reported for images can be incorrect. It might report that it can reclaim more than a prune would actually free. This will happen if you are using different images that share some layers.
OPTIONS

| .Size | Size of each type (human-readable) |
