.SH "NAME"
groupadd \- erstellt eine neue Gruppe
.SH "\(:UBERSICHT"
.HP \w'\fBgroupadd\fR\ 'u
\fBgroupadd\fR [\fIOPTIONEN\fR] \fINEWGROUP\fR
.SH "BESCHREIBUNG"
.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\&.
.PP
Groupnames may contain only lower and upper case letters, digits, underscores, or dashes\&. They can end with a dollar sign\&. Dashes are not allowed at the beginning of the groupname\&. Fully numeric groupnames and groupnames \&. or \&.\&. are also disallowed\&.
.PP
Groupnames may only be up to 32 characters long\&.
.SH "OPTIONEN"
.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\&.
\fIGID\fR
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

.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
permits the creation of a group with an already used numerical ID\&. As a result, for this
\fIGID\fR, the mapping towards group
\fINEWGROUP\fR
may not be unique\&.
.RE
.PP
\fB\-p\fR, \fB\-\-password\fR\ \&\fIPASSWORD\fR
.RS 4
defines an initial password for the group account\&. PASSWORD is expected to be encrypted, as returned by
\fBcrypt \fR(3)\&.
.sp
Without this option, the group account will be locked and with no password defined, i\&.e\&. a single exclamation mark in the respective field of ths system account file
/etc/group
or
/etc/gshadow\&.
.sp
\fBNote:\fR
This option is not recommended because the password (or encrypted password) will be visible by users listing the processes\&.
.sp
Sie sollten sicherstellen, dass das Passwort den Passwortrichtlinien des Systems entspricht\&.
.RE
.PP
\fB\-r\fR, \fB\-\-system\fR
.RS 4
erstellt eine neue Systemgruppe
.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\&. Only absolute paths are supported\&.
.RE
.PP
\fB\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR
.RS 4
Apply changes to configuration files under the root filesystem found under the directory
\fIPREFIX_DIR\fR\&. 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
.PP
\fB\-U\fR, \fB\-\-users\fR
.RS 4
A list of usernames to add as members of the group\&.
.sp
The default behavior (if the
\fB\-g\fR,
\fB\-N\fR, and
\fB\-U\fR
options are not specified) is defined by the
\fBUSERGROUPS_ENAB\fR
variable in
/etc/login\&.defs\&.
.RE
.SH "KONFIGURATION"

/etc/login\&.defs

If the groupname already exists in an external group database such as NIS or LDAP,
\fBgroupadd\fR
will deny the group creation request\&.
