lxc-cgroup(1)                                              lxc-cgroup(1)

NAME         top

       lxc-cgroup - manage the control group associated with a container

SYNOPSIS         top

       lxc-cgroup {-n name} {state-object} [value]

DESCRIPTION         top

       lxc-cgroup  gets  or  sets  the  value  of  a state-object (e.g.,
       'cpuset.cpus') in the container's cgroup  for  the  corresponding
       subsystem  (e.g., 'cpuset'). If no [value] is specified, the cur‐
       rent value of the state-object is displayed; otherwise it is set.

       Note that lxc-cgroup does not  check  that  the  state-object  is
       valid for the running kernel, or that the corresponding subsystem
       is contained in any mounted cgroup hierarchy.
