+
+## NAME
+podman\-pod\-kill - Kills all containers in one or more pods with a signal
+
+## SYNOPSIS
+**podman pod kill** [*options*] *pod* ...
+
+## DESCRIPTION
+The main process of each container inside the pods specified will be sent SIGKILL, or any signal specified with option --signal.
+
+## OPTIONS
+**--all, -a**
+
+Sends signal to all containers associated with a pod.
+
+**--latest, -l**
+
+Instead of providing the pod name or ID, use the last created pod. If you use methods other than Podman
+to run pods such as CRI-O, the last started pod could be from either of those methods.
+
+**--signal, s**
+
+Signal to send to the containers in the pod. For more information on Linux signals, refer to *man signal(7)*.
+
+
+## EXAMPLE
+
+podman pod kill mywebserver
+
+podman pod kill 860a4b23
+
+podman pod kill --signal TERM 860a4b23
+
+podman pod kill --latest
+
+podman pod kill --all
