lssubsys [-m|--mount-points] [-M|--all-mount-points] [-i|--hierarchies] [-a|--all]
lssubsys list the hierarchies containing the given subsystem(s). If no subsystem is defined, it displays all mounted hierarchies.
defines the subsystem whose hierarchy is shown. If this parameter is not used, the command will list all mounted subsystems.
- -m, --mount-points
Display mount points. Only the first mount points of shown hierarchies are displayed.
- -M, --all-mount-points
Display mount points. All mount points of shown hierarchies are displayed, each on separate line.
- -a, --all
Display all subsystems (including unmounted ones).
- -i, --hierarchies
Display the attached hierarchy number if the subsystem is in a hierarchy. If the option -m is also used, the hierarchy number is shown only for unmounted hierarchies.
- -h, --help
Display help and exit.
The command lssubsys -am lists all subsystems which are present in the system, mounted ones will be shown with their mount point:
$ lssubsys -am ns cpuset cpu,devices cpuacct /cgroup/cpuacct memory /cgroup/memory freezer /cgroup/freezer net_cls /cgroup/net_cls
The command lssubsys -ami lists all subsystems which are present in the system, mounted subsystems are listed with their mount points, unmounted ones which are in a hierarchy are listed with their hierarchy number:
$ lssubsys -ami ns cpuset 5 cpu,devices 6 cpuacct /cgroup/cpuacct memory /cgroup/memory freezer /cgroup/freezer net_cls /cgroup/net_cls
lssubsys is currently supported on cgroups v1 only.
