.SH "SYNOPSIS"
.HP \w'\fBgroupadd\fR\ 'u
\fBgroupadd\fR [\fIflaggor\fR] \fIgrupp\fR
.SH "BESKRIVNING"
.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 "FLAGGOR"

.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

This option permits to add a group with a non\-unique GID\&.
.RE
.PP
\fB\-p\fR, \fB\-\-password\fR\ \&\fIL\(:OSENORD\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
You should make sure the password respects the system\*(Aqs password policy\&.
.RE
.PP
\fB\-r\fR, \fB\-\-system\fR
.RS 4
Create a system group\&.
.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
.SH "CONFIGURATION"
.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
The default value is 0, meaning that there are no limits in the number of members in a group\&.
.sp
This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.
.sp
If you need to enforce such limit, you can use 25\&.
.sp
Note: split groups may not be supported by all tools (even in the Shadow toolsuite)\&. You should not use this variable unless you really need it\&.
.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)\&.

Groupnames must start 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
Groupnames may only be up to 16 characters long\&.
.PP
You may not add a NIS or LDAP group\&. This must be performed on the corresponding server\&.
.PP
If the groupname already exists in an external group database such as NIS or LDAP,
\fBgroupadd\fR
will deny the group creation request\&.
