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