## 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  control
              group’s  files.  These  users  are allowed to set subsystem parameters and create sub‐
              groups.  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 spec‐
              ified 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.  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  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  con‐
              trol  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.
