12 [-s mode] -g <controllers>:<path> [-g ...]

16 The command creates new cgroup(s) defined by the options -g.
17
18
19 -a <agid>:<auid>
20 defines the name of the user and the group which own the rest of
21 the defined control group’s files. These users are allowed to
22 set subsystem parameters and create subgroups. The default
23 value is the same as has the parent cgroup.
24
25
26 -d, --dperm=mode
27 sets the permissions of a control groups directory. The permis‐
28 sions needs to be specified as octal numbers e.g. -d 775.
29
30
31 -f, --fperm=mode
32 sets the permissions of the control groups parameters. The per‐
33 missions needs to be specified as octal numbers e.g. -f 775.
34 The value is not used as given because the current owner's per‐
35 missions are used as an umask (so 777 will set group and others
36 permissions to the owners permissions).
37
38
39 -g <controllers>:<path>
40 defines control groups to be added. controllers is a list of
41 controllers. Character "*" can be used as a shortcut for "all
42 mounted controllers". path is the relative path to control
43 groups in the given controllers list. This option can be speci‐
44 fied multiple times.

51 -s, --tperm=mode
52 sets the permissions of the control group tasks file. The per‐
53 missions needs to be specified as octal numbers e.g. -s 775.
54 The value is not used as given because the current owner's per‐
55 missions are used as an umask (so 777 will set group and others
56 permissions to the owners permissions).
57
58
59 -t <tuid>:<tgid>
60 defines the name of the user and the group, which owns tasks
61 file of the defined control group. I.e. this user and members of
