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
