<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>
