Primary Versus Secondary Groups
One final note on groups is that it is important to understand the difference between the primary and secondary group. A user can only be a member of one primary group. The primary group is the group that any files they create will belong to by default. However, a user can be a member of multiple secondary groups.
The primary group is the one that is listed in the /etc/passwd file along with the user's entry. Any other group that the user is a member of in /etc/group is considered to be a secondary group.

NAME
groupadd - add a new group to the system
SYNOPSIS
gid group
DESCRIPTION
The command creates a new group on the system by adding the appropriate entry to the file. The command must be used with the group argu-
ment, which is the name of the new group. The name consists of a string of printable characters that may not include a colon or newline
Refer to usergroupname(5) to understand the functionality changes with the Numeric User Group Name feature.
Options
The command uses the following options:
Specify the group ID
for the new group. gid must be a non-negative decimal integer less than as defined in the header file. By default the
next available unique group ID in the valid range is allocated. Group IDs in the range 0-99 are reserved.
Allow the gid to be non-unique (that is, a duplicate).
NIS
The command is aware of NIS user entries. Only local groups may be added with this command. Attempts to add an NIS group will result in
an error. NIS groups must be administered from the NIS server. If is used on a system where NIS is installed, it may fail with the error
(return value 9) if the group specified is not present in the local file, but is an NIS group (see group(4)). NIS groups are also checked
when verifying uniqueness of the new gid, which may result in the error
(return value 4).
RETURN VALUE
The command exits with one of the following values:
No error.
Invalid command syntax.
Invalid argument supplied to an option.
gid is not unique (when is not used).
group
is not unique.
Cannot modify the
file.
file or
file busy. Another command may be modifying the file.
Unable to open
file or file is non-existent.
EXAMPLES
Add the group to the file.
Add the group to the file with the group ID as long as no group currently exists with a group ID of
WARNINGS
Because many users may try to write the file simultaneously, a password locking mechanism was devised. If this locking fails after subse-
quent retrying, terminates.
