groupadd(1M) SYSTEM ADMINISTRATION COMMANDS groupadd(1M)
NAME
groupadd - add (create) a new group definition on the system
SYNOPSIS
groupadd [-g gid [-o]] group
DESCRIPTION
The groupadd command creates a new group definition on the
system by adding the appropriate entry to the /etc/group
file. The following options are available:
-g gid
The group id for the new group. This group id must be
a non-negative decimal integer below MAXUID as defined
in the <param.h> header file. The group ID defaults to
the next available (unique) number above the highest
number currently assigned. For example, if groups 100,
105, and 200 are assigned as groups, the next default
group number will be 201. (Group IDs from 0-99 are
reserved.)
-o This option allows the gid to be duplicated (non-
unique).
group
A string of printable characters that specifies the
name of the new group. It may not include a colon (:)
or newline (\\n).
