<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>

<para>By default, empty control groups are not shown.</para>
