CGSET(1)                       libcgroup Manual                       CGSET(1)



NAME
       cgset - set the parameters of given cgroup(s)


SYNOPSIS
       cgset [-b] [-R] [-r <name=value>] <cgroup_path> ...
       cgset [-b] [-R] --copy-from <source_cgroup_path> <cgroup_path> ...


DESCRIPTION
       Set the parameters of input cgroups.


       <path> is the name of the cgroup which should be changed.  This
              parameter can be used multiple times.


       -b     ignores the default systemd delegated hierarchy path and
              constructs the path of the control groups relative to the cgroup
              root hierarchy.


       -r <name=value>
              defines the name of the file to set and the value which should
              be written to that file.  This parameter can be used multiple
              times.


       -R     recursively sets variable settings passed with -r option to
              cgroup_path and its descendant cgroups.


       --copy-from <source_cgroup_path>
              defines the name of the cgroup whose parameters will be copied
              to the input cgroup.


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


EXAMPLES
       cgset -r cpuset.cpus=0-1 student
              set variable cpus in control group student (controller cpuset)
              to 0-1


       cgset --copy-from group1/ group2/
              copy all parameters of group group1 to group group2 (for all
              path where both cgroups are defined)
