$ cgcreate -g cpu:mygroup

$ cgcreate -g cpu,memory:mygroup

$ cgcreate -g *:mygroup

$ cgcreate -t user:group -g cpu:mygroup

$ cgcreate -a user:group -g cpu:mygroup

$ cgcreate -d 755 -g cpu:mygroup

cgcreate [-h] [-t tuid:tgid] [-a agid:auid] [-f mode] [-d mode] -g controllers:path [-g ...]

Set ownership of control files (determines who can modify parameters)

Set directory permissions in octal notation (e.g., 755)

Set parameter file permissions in octal notation

Set tasks file permissions in octal notation

Cgroups v1 and v2 have different hierarchies and features. On cgroups v2 systems, the syntax and available controllers may differ. Created cgroups persist until deleted with cgdelete or system reboot.

cgcreate is part of libcgroup, providing user-space tools for managing Linux control groups which were introduced in kernel 2.6.24.
