The Linux common command groupadd command is used to create a new workgroup, and the information for the new workgroup is added to the system file.

Syntax groupadd command syntax format is as follows:

Groupadd [- g gid [- o]] [- r] [- f] group parameter description:

-g: specify the id of the new workgroup

-r: create a system workgroup whose group ID is less than 500

-K: overwrite the configuration file "/ ect/login.defs"

-o: allows you to add workgroups whose group ID number is not unique.

-fjour force: if the specified group already exists, this option will be blind and exit only in a successful state. When used with-g and the specified GID_MIN already exists, select another unique GID (that is,-g off).

Instance to create a new group and add the group ID.

# groupadd-g 344 runoob now produces an item with a group ID (GID) of 344 in the / etc/group file.
