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