containers will not be stopped and will only be started.
## OPTIONS
-**--timeout**
-
-Timeout to wait before forcibly stopping the container
+**--all, -a**
+Restart all containers regardless of their current state.
**--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.
+**--running**
+Restart all containers that are already in the *running* state.
+
+**--timeout**
+Timeout to wait before forcibly stopping the container.
+
+
## EXAMPLES ##
+Restart the latest container
```
$ podman restart -l
