**podman container top** [*options*] *container* [*format-descriptors*]
## DESCRIPTION
-Display the running processes of the container. The *format-descriptors* are ps (1) compatible AIX format descriptors but extended to print additional information, such as the seccomp mode or the effective capabilities of a given process. The descriptors can either be passed as separated arguments or as a single comma-separated argument. Note that you can also specify options and or flags of ps(1); in this case, Podman will fallback to executing ps with the specified arguments and flags in the container.
+Display the running processes of the container. The *format-descriptors* are ps (1) compatible AIX format descriptors but extended to print additional information, such as the seccomp mode or the effective capabilities of a given process. The descriptors can either be passed as separated arguments or as a single comma-separated argument. Note that you can also specify options and or flags of ps(1); in this case, Podman will fallback to executing ps with the specified arguments and flags in the container. Please use the "h*" descriptors if you want to extract host-related information. For instance, `podman top $name hpid huser` to display the PID and user of the processes in the host context.
