| |
| <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> |
