DESCRIPTION
===========
- **bpftool cgroup { show | list }** *CGROUP*
+ **bpftool cgroup { show | list }** *CGROUP* [**effective**]
List all programs attached to the cgroup *CGROUP*.
Output will start with program ID followed by attach type,
attach flags and program name.
- **bpftool cgroup tree** [*CGROUP_ROOT*]
+ If **effective** is specified retrieve effective programs that
+ will execute for events within a cgroup. This includes
+ inherited along with attached ones.
+
+ **bpftool cgroup tree** [*CGROUP_ROOT*] [**effective**]
Iterate over all cgroups in *CGROUP_ROOT* and list all
attached programs. If *CGROUP_ROOT* is not specified,
bpftool uses cgroup v2 mountpoint.

commands: it starts with absolute cgroup path, followed by
