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
70                 to. Otherwise the full systemd control group hierarchy
