LSSUBSYS(1)                               libcgroup Manual                               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  op‐
              tion -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  sub‐
       systems  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


ENVIRONMENT VARIABLES
       CGROUP_LOGLEVEL
              controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR.
