LSSUBSYS(1)

NAME

lssubsys - list hierarchies containing given subsystem

SYNOPSIS
lssubsys [-m|--mount-points] [-M|--all-mount-points] [controller] [...]
lssubsys [-m|--mount-points] [-M|--all-mount-points] [-i|--hierarchies] [-a|--all]
lssubsys [-h|--help]

DESCRIPTION
lssubsys list the hierarchies containing the given subsystem(s). If no subsystem is defined, it displays all mounted hierarchies.

controller
    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.

EXAMPLE
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
