groupadd \- создаёт новую группу
.SH "СИНТАКСИС"

\fBgroupadd\fR [\fIпараметры\fR] \fIгруппа\fR
.SH "ОПИСАНИЕ"
.PP
The
\fBgroupadd\fR
command creates a new group account using the values specified on the command line plus the default values from the system\&. The new group will be entered into the system files as needed\&.
.SH "ПАРАМЕТРЫ"
.PP
The options which apply to the
\fBgroupadd\fR
command are:
.PP
\fB\-f\fR, \fB\-\-force\fR
.RS 4
This option causes the command to simply exit with success status if the specified group already exists\&. When used with
\fB\-g\fR, and the specified GID already exists, another (unique) GID is chosen (i\&.e\&.
\fB\-g\fR
is turned off)\&.
.RE
.PP
\fB\-g\fR, \fB\-\-gid\fR\ \&\fIGID\fR
.RS 4
The numerical value of the group\*(Aqs ID\&. This value must be unique, unless the
\fB\-o\fR
option is used\&. The value must be non\-negative\&. The default is to use the smallest ID value greater than or equal to
\fBGID_MIN\fR
and greater than every other group\&.
.sp
See also the
\fB\-r\fR
option and the
\fBGID_MAX\fR
description\&.
.RE
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Показать краткую справку и закончить работу\&.
.RE
.PP
\fB\-K\fR, \fB\-\-key\fR\ \&\fIKEY\fR=\fIVALUE\fR
.RS 4
Overrides
/etc/login\&.defs
defaults (GID_MIN, GID_MAX and others)\&. Multiple
\fB\-K\fR
options can be specified\&.
.sp
Example:
\fB\-K\fR\ \&\fIGID_MIN\fR=\fI100\fR\ \&
\fB\-K\fR\ \&\fIGID_MAX\fR=\fI499\fR
.sp
Note:
\fB\-K\fR\ \&\fIGID_MIN\fR=\fI10\fR,\fIGID_MAX\fR=\fI499\fR
doesn\*(Aqt work yet\&.
.RE
.PP
\fB\-o\fR, \fB\-\-non\-unique\fR
.RS 4
Разрешить добавление группы с не уникальным GID\&.
.RE
.PP
\fB\-p\fR, \fB\-\-password\fR\ \&\fIPASSWORD\fR
.RS 4
The encrypted password, as returned by
\fBcrypt\fR(3)\&. The default is to disable the password\&.
.sp
\fBNote:\fR
This option is not recommended because the password (or encrypted password) will be visible by users listing the processes\&.
.sp
Вы должны проверить, что пароль соответствует политике системных паролей\&.
.RE
.PP
\fB\-r\fR, \fB\-\-system\fR
.RS 4
Создать системную группу\&.
.sp
The numeric identifiers of new system groups are chosen in the
\fBSYS_GID_MIN\fR\-\fBSYS_GID_MAX\fR
range, defined in
login\&.defs, instead of
\fBGID_MIN\fR\-\fBGID_MAX\fR\&.
.RE
.PP
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
.RS 4
Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&.
.RE
.PP
\fB\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR
.RS 4
Apply changes in the
\fIPREFIX_DIR\fR
directory and use the configuration files from the
\fIPREFIX_DIR\fR
directory\&. This option does not chroot and is intended for preparing a cross\-compilation target\&. Some limitations: NIS and LDAP users/groups are not verified\&. PAM authentication is using the host files\&. No SELINUX support\&.
.RE
.SH "НАСТРОЙКА"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.PP
\fBGID_MAX\fR (number), \fBGID_MIN\fR (number)
.RS 4
Range of group IDs used for the creation of regular groups by
\fBuseradd\fR,
\fBgroupadd\fR, or
\fBnewusers\fR\&.
.sp
The default value for
\fBGID_MIN\fR
(resp\&.
\fBGID_MAX\fR) is 1000 (resp\&. 60000)\&.
.RE
.PP
\fBMAX_MEMBERS_PER_GROUP\fR (number)
.RS 4
Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
/etc/group
(with the same name, same password, and same GID)\&.
.sp
Значение по умолчанию равно 0, означающее, что ограничения на количество членов в группе нет\&.
.sp
Данная возможность (разделение группы) позволяет ограничить длину строк в файле групп\&. Это полезно для ограничения длины строк групп NIS в 1024 символа\&.
.sp
Если вам нужно такое ограничение, укажите значение 25\&.
.sp
Замечание: разделение групп поддерживается не всеми инструментами (даже в наборе инструментов Shadow)\&. Вы не должны использовать эту переменную, если вам действительно это ненужно\&.
.RE
.PP
\fBSYS_GID_MAX\fR (number), \fBSYS_GID_MIN\fR (number)
.RS 4
Range of group IDs used for the creation of system groups by
\fBuseradd\fR,
\fBgroupadd\fR, or
\fBnewusers\fR\&.
.sp
The default value for
\fBSYS_GID_MIN\fR
(resp\&.
\fBSYS_GID_MAX\fR) is 101 (resp\&.
\fBGID_MIN\fR\-1)\&.

.SH "ПРЕДОСТЕРЕЖЕНИЯ"
.PP
It is usually recommended to only use groupnames that begin with a lower case letter or an underscore, followed by lower case letters, digits, underscores, or dashes\&. They can end with a dollar sign\&. In regular expression terms: [a\-z_][a\-z0\-9_\-]*[$]?
.PP
On Debian, the only constraints are that groupnames must neither start with a dash (\*(Aq\-\*(Aq) nor plus (\*(Aq+\*(Aq) nor tilde (\*(Aq~\*(Aq) nor contain a colon (\*(Aq:\*(Aq), a comma (\*(Aq,\*(Aq), or a whitespace (space:\*(Aq \*(Aq, end of line: \*(Aq\en\*(Aq, tabulation: \*(Aq\et\*(Aq, etc\&.)\&.
.PP
Groupnames may only be up to 32 characters long\&.
.PP
Нельзя добавить группу NIS или LDAP\&. Это необходимо делать на соответствующем сервере\&.
.PP
If the groupname already exists in an external group database such as NIS or LDAP,
\fBgroupadd\fR
will deny the group creation request\&.
