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 and  path
              is  the  relative path to control groups in the given controllers list. This option
              can be specified 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.
