groupmod(1M) groupmod(1M)
NAME
groupmod - modify a group definition on the system
SYNOPSIS
groupmod [-g gid [-o]] [-n name] group
DESCRIPTION
The groupmod command modifies the definition of the specified group by
modifying the appropriate entry in the /etc/group file.
OPTIONS
-g gid The group id for the new group. This group id must be a
non-negative decimal integer below 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.)
-o This option allows the gid to be duplicated (non-unique).
-n name A string of printable characters that specifies a new name
for the group. It may not include a colon (:) or newline
(\n).
group The current name of the group to be modified.
DIAGNOSTICS
The command 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.
LOCALE
The LCMESSAGES environment variable governs the language in which
message texts are displayed.
If LCMESSAGES is undefined or is defined as the null string, it
defaults to the value of LANG. If LANG is likewise undefined or null,
the system acts as if it were not internationalized.
If any of the locale variables has an invalid value, the system acts
as if none of the variables was set.
The LCALL environment variable governs the entire locale. LCALL
takes precedence over all the other environment variables which affect
internationalization.
