+
+ <para><command>systemd-cgls</command> recursively shows the
+ contents of the selected Linux control group hierarchy in a tree.
+ If arguments are specified, shows all member processes of the
+ specified control groups plus all their subgroups and their
+ members. The control groups may either be specified by their full
+ file paths or are assumed in the systemd control group hierarchy.
+ If no argument is specified and the current working directory is
+ beneath the control group mount point
+ <filename>/sys/fs/cgroup</filename>, shows the contents of the
+ control group the working directory refers to. Otherwise, the full
+ systemd control group hierarchy is shown.</para>
