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