 ## OPTIONS
+
 #### **--all**, **-a**
+
 Restart all containers regardless of their current state.
 
+#### **--cidfile**
+
+Read container ID from the specified file and restart the container.  Can be specified multiple times.
+
+#### **--filter**, **-f**=*filter*
+
+Filter what containers restart.
+Multiple filters can be given with multiple uses of the --filter flag.
+Filters with the same key work inclusive with the only exception being
+`label` which is exclusive. Filters with different keys always work exclusive.
+
+Valid filters are listed below:

+| name            | [Name] Container's name (accepts regex)                                          |
+| label           | [Key] or [Key=Value] Label assigned to a container                               |

+| status          | [Status] Container's status: 'created', 'exited', 'paused', 'running', 'unknown' |
+| ancestor        | [ImageName] Image or descendant used to create container                         |
+| before          | [ID] or [Name] Containers created before this container                          |
+| since           | [ID] or [Name] Containers created since this container                           |
+| volume          | [VolumeName] or [MountpointDestination] Volume mounted in container              |
+| health          | [Status] healthy or unhealthy                                                    |

+
 #### **--latest**, **-l**
+
 Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
 to run containers such as CRI-O, the last started container could be from either of those methods. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
 
 #### **--running**

 Restart all containers that are already in the *running* state.
