NAME
cgcreate - create new cgroup(s)
SYNOPSIS
cgcreate [-h] [-t <tuid>:<tgid>] [-a <agid>:<auid>] [-f mode] [-d mode]
[-s mode] -g <controllers>:<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 control 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 permis-
sions needs to be specified as octal numbers e.g. -d 775.
-f, --fperm=mode
sets the permissions of the control groups parameters. The per-
missions needs to be specified as octal numbers e.g. -f 775.
The value is not used as given because the current owner's per-
missions 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. Character "*" can be used as a shortcut for "all
mounted controllers". path is the relative path to control
groups in the given controllers list. This option can be speci-
fied multiple times.
-h, --help
display this help and exit
-s, --tperm=mode
sets the permissions of the control group tasks file. The per-
missions needs to be specified as octal numbers e.g. -s 775.
The value is not used as given because the current owner's per-
missions 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.
