groupmod(8) System Administration Commands groupmod(8)
NAME
groupmod - modify a group definition on the system
SYNOPSIS
/usr/sbin/groupmod [-S repository] [-g gid [-o]] [-n name]
[-U [+|-]user1[,user2]...] group
DESCRIPTION
The groupmod command modifies the definition of the specified group by
modifying the appropriate entry in the group database in the reposi‐
tory.
An administrator can modify any group for which it has a matching au‐
thorization of the form solaris.group.assign/groupname. This authoriza‐
tion is automatically assigned to the administrator who created the
group. An administrator must have solaris.group.assign authorization to
modify all other groups.
OPTIONS
The following options are supported:
-g gid
Specify the new group ID for the group. This group ID must be a
non-negative decimal integer less than MAXUID, as defined in
<param.h>. The group ID defaults to the next available (unique)
number above 99. (Group IDs from 0-99 are reserved by Oracle So‐
laris for future applications.)
-n name
Specify the new name for the group. The name argument is a string
of no more than 32 bytes consisting of characters from the set of
ASCII lowercase alphabetic characters and numeric characters. A
warning message will be written if these restrictions are not met.
A future Oracle Solaris release may refuse to accept group fields
that do not meet these requirements. The name argument must contain
at least one character and must not include a colon (:) or NEWLINE
(\n).
-o
Allow the gid to be duplicated (non-unique). An administrator must
have solaris.group.assign authorization to use this option.
-S repository
The repository specifies which name service will be updated. The
valid repositories are files and ldap. The default repository is
files. When the repository is files, the user names can be present
in other name service repositories and can be assigned to a group
in the files repository. When the repository is ldap, all the as‐
signable attributes must be present in the ldap repository, and
both the LDAP server and client must be configured with enableShad‐
owUpdate. See ldapclient(8) for details.
-U [+|-]user1[,user2]
Updates the list of users for the group as follows:
o A prefix + before the list adds that list to existing
users list.
o A prefix - before the list removes each user in the list
from the existing users list.
o With no prefix before the list, replaces the existing
users list with the new list of users specified.
OPERANDS
The following operands are supported:
group An existing group name to be modified.
EXIT STATUS
The groupmod utility exits with one of the following values:
0 Success.
2 Invalid command syntax. A usage message for the groupmod command
is displayed.
3 An invalid argument was provided to an option.
4 gid is not unique (when the -o option is not used).
6 group does not exist.
9 name already exists as a group name.
10 Cannot update the /etc/group file.

NOTES
The groupmod utility modifies group definitions in the group database
in the repository. If a network name service is being used to supple‐
ment the local /etc/group file with additional entries, groupmod veri‐
fies the uniqueness of a specified group name and group ID against the
external name service and uses the entries in the files repository. The
group name should be restricted to the Portable Filename Characters: A-
Z, a-z, 0-9, '_', '-', and '.'.
groupmod fails if a group entry (a single line in /etc/group) exceeds
2047 characters.
