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