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 parame-
ter is not used, the command will list all mounted subsystems.
-m, --mount-points
Display mount points. Only the first mount points of shown hier-
archies 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, un-
mounted 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
