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