51 | <title>Description</title> | |
52 | ||
53 | <para><command>systemd-cgls</command> recursively shows the | |
54 | contents of the selected Linux control group hierarchy in a tree. | |
55 | If arguments are specified, shows all member processes of the | |
56 | specified control groups plus all their subgroups and their | |
57 | members. The control groups may either be specified by their full | |
58 | file paths or are assumed in the systemd control group hierarchy. | |
59 | If no argument is specified and the current working directory is | |
60 | beneath the control group mount point | |
61 | <filename>/sys/fs/cgroup</filename>, shows the contents of the | |
62 | control group the working directory refers to. Otherwise, the full | |
63 | systemd control group hierarchy is shown.</para> | |
64 | ||
65 | <para>By default, empty control groups are not shown.</para> | |
