NAME
cgcreate - create new cgroup(s)
SYNOPSIS
cgcreate [-h] [-t <tuid>:<tgid>] [-a <agid>:<auid>] [-f mode] [-d mode] [-s mode] -g <con-
trollers>:<path> [-g ...]
DESCRIPTION
The command creates new cgroup(s) defined by the options -g.
-a <agid>:<auid>
defines the name of the user and the group which own the rest of the defined con-
trol group's files. These users are allowed to set subsystem parameters and create
subgroups. The default value is the same as has the parent cgroup.
-d, --dperm=mode
sets the permissions of a control groups directory. The permissions needs to be
specified as octal numbers e.g. -d 775.
-f, --fperm=mode
sets the permissions of the control groups parameters. The permissions needs to be
specified as octal numbers e.g. -f 775. The value is not used as given because
the current owner's permissions are used as an umask (so 777 will set group and
others permissions to the owners permissions).
-g <controllers>:<path>
defines control groups to be added. controllers is a list of controllers. Charac-
ter "*" can be used as a shortcut for "all mounted controllers". path is the rela-
tive path to control groups in the given controllers list. This option can be spec-
ified multiple times.
-h, --help
display this help and exit
-s, --tperm=mode
sets the permissions of the control group tasks file. The permissions needs to be
specified as octal numbers e.g. -s 775. The value is not used as given because
the current owner's permissions are used as an umask (so 777 will set group and
others permissions to the owners permissions).
-t <tuid>:<tgid>
defines the name of the user and the group, which owns tasks file of the defined
control group. I.e. this user and members of this group have write access to the
file. The default value is the same as has the parent cgroup.
