| <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> |
