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
