On Debian, administrators should usually use \fBadduser\fR(8) instead\&. .PP When invoked without the \fB\-D\fR option, the \fBuseradd\fR command creates a new user account using the values specified on the command line plus the default values from the system\&. Depending on command line options, the \fBuseradd\fR command will update system files and may also create the new user\*(Aqs home directory and copy initial files\&. .PP By default, a group will also be created for the new user (see \fB\-g\fR, \fB\-N\fR, \fB\-U\fR, and \fBUSERGROUPS_ENAB\fR)\&. .SH "OPTIONEN" .PP The options which apply to the \fBuseradd\fR command are: .PP \fB\-\-badname\fR\ \& .RS 4 Allow names that do not conform to standards\&. .RE .PP \fB\-b\fR, \fB\-\-base\-dir\fR\ \&\fIBASE_DIR\fR .RS 4 The default base directory for the system if \fB\-d\fR\ \&\fIHOME_DIR\fR is not specified\&. \fIBASE_DIR\fR is concatenated with the account name to define the home directory\&. If the \fB\-m\fR option is not used, \fIBASE_DIR\fR must exist\&. .sp If this option is not specified, \fBuseradd\fR will use the base directory specified by the \fBHOME\fR variable in /etc/default/useradd, or /home by default\&. .RE .PP \fB\-c\fR, \fB\-\-comment\fR\ \&\fICOMMENT\fR .RS 4 Eine beliebige Zeichenkette\&. Dies ist f\(:ur gew\(:ohnlich eine kurze Beschreibung des Logins und wird im Moment im Feld f\(:ur den vollst\(:andigen Namen des Benutzers gespeichert\&. .RE .PP \fB\-d\fR, \fB\-\-home\-dir\fR\ \&\fIHOME_DIR\fR .RS 4 The new user will be created using \fIHOME_DIR\fR as the value for the user\*(Aqs login directory\&. The default is to append the \fILOGIN\fR name to \fIBASE_DIR\fR and use that as the login directory name\&. The directory \fIHOME_DIR\fR does not have to exist but will not be created if it is missing\&. .RE .PP \fB\-D\fR, \fB\-\-defaults\fR .RS 4 Lesen Sie dazu unten den Abschnitt \(FcDie Standardwerte ver\(:andern\(Fo\&. .RE .PP \fB\-e\fR, \fB\-\-expiredate\fR\ \&\fIEXPIRE_DATE\fR .RS 4 The date on which the user account will be disabled\&. The date is specified in the format \fIYYYY\-MM\-DD\fR\&. .sp If not specified, \fBuseradd\fR will use the default expiry date specified by the \fBEXPIRE\fR variable in /etc/default/useradd, or an empty string (no expiry) by default\&. .RE .PP \fB\-f\fR, \fB\-\-inactive\fR\ \&\fIINACTIVE\fR .RS 4 Die Anzahl von Tagen nach Ablaufen des Passworts bis das Konto dauerhaft deaktiviert wird\&.

Der Gruppenname muss existieren\&. Die Gruppenzahl muss auf eine bereits vorhandene Gruppe verweisen\&. .sp If not specified, the behavior of \fBuseradd\fR will depend on the \fBUSERGROUPS_ENAB\fR variable in /etc/login\&.defs\&. If this variable is set to \fIyes\fR (or \fB\-U/\-\-user\-group\fR is specified on the command line), a group will be created for the user, with the same name as her loginname\&. If the variable is set to \fIno\fR (or \fB\-N/\-\-no\-user\-group\fR is specified on the command line), useradd will set the primary group of the new user to the value specified by the \fBGROUP\fR variable in /etc/default/useradd, or 100 by default\&. .RE .PP \fB\-G\fR, \fB\-\-groups\fR\ \&\fIGROUP1\fR[\fI,GROUP2,\&.\&.\&.\fR[\fI,GROUPN\fR]]] .RS 4 A list of supplementary groups which the user is also a member of\&. Each group is separated from the next by a comma, with no intervening whitespace\&. The groups are subject to the same restrictions as the group given with the \fB\-g\fR option\&. The default is for the user to belong only to the initial group\&. .RE .PP \fB\-h\fR, \fB\-\-help\fR .RS 4 zeigt die Hilfe an und beendet das Programm .RE .PP \fB\-k\fR, \fB\-\-skel\fR\ \&\fISKEL_DIR\fR .RS 4 The skeleton directory, which contains files and directories to be copied in the user\*(Aqs home directory, when the home directory is created by \fBuseradd\fR\&. .sp This option is only valid if the \fB\-m\fR (or \fB\-\-create\-home\fR) option is specified\&. .sp If this option is not set, the skeleton directory is defined by the \fBSKEL\fR variable in /etc/default/useradd or, by default, /etc/skel\&. .sp Soweit m\(:oglich, werden die ACLs und erweiterten Attribute kopiert\&. .RE .PP \fB\-K\fR, \fB\-\-key\fR\ \&\fIKEY\fR=\fIVALUE\fR .RS 4 Overrides /etc/login\&.defs defaults (\fBUID_MIN\fR, \fBUID_MAX\fR, \fBUMASK\fR, \fBPASS_MAX_DAYS\fR and others)\&. Example: \fB\-K\fR\ \&\fIPASS_MAX_DAYS\fR=\fI\-1\fR can be used when creating system account to turn off password aging, even though system account has no password at all\&. Multiple \fB\-K\fR options can be specified, e\&.g\&.: \fB\-K\fR\ \&\fIUID_MIN\fR=\fI100\fR\ \& \fB\-K\fR\ \&\fIUID_MAX\fR=\fI499\fR .RE .PP \fB\-l\fR, \fB\-\-no\-log\-init\fR .RS 4 F\(:ugt den Benutzer nicht zu den Datenbanken lastlog und faillog hinzu\&. .sp By default, the user\*(Aqs entries in the lastlog and faillog databases are reset to avoid reusing the entry from a previously deleted user\&. .sp For the compatibility with previous Debian\*(Aqs \fBuseradd\fR, the \fB\-O\fR option is also supported\&. .RE .PP \fB\-m\fR, \fB\-\-create\-home\fR .RS 4 Create the user\*(Aqs home directory if it does not exist\&. The files and directories contained in the skeleton directory (which can be defined with the \fB\-k\fR option) will be copied to the home directory\&. .sp By default, if this option is not specified and \fBCREATE_HOME\fR is not enabled, no home directories are created\&. .RE .PP \fB\-M\fR, \fB\-\-no\-create\-home\fR .RS 4 Do no create the user\*(Aqs home directory, even if the system wide setting from /etc/login\&.defs (\fBCREATE_HOME\fR) is set to \fIyes\fR\&. .RE .PP \fB\-N\fR, \fB\-\-no\-user\-group\fR .RS 4 Do not create a group with the same name as the user, but add the user to the group specified by the \fB\-g\fR option or by the \fBGROUP\fR variable in /etc/default/useradd\&. .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 .PP \fB\-o\fR, \fB\-\-non\-unique\fR .RS 4 Erlaubt das Erstellen eines Benutzerkontos mit einer schon vergebenen (nicht eindeutigen) UID\&. .sp This option is only valid in combination with the \fB\-u\fR option\&. .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 Sie sollten sicherstellen, dass das Passwort den Passwortrichtlinien des Systems entspricht\&. .RE .PP \fB\-r\fR, \fB\-\-system\fR .RS 4 erstellt ein Systemkonto .sp System users will be created with no aging information in /etc/shadow, and their numeric identifiers are chosen in the \fBSYS_UID_MIN\fR\-\fBSYS_UID_MAX\fR range, defined in /etc/login\&.defs, instead of \fBUID_MIN\fR\-\fBUID_MAX\fR (and their \fBGID\fR counterparts for the creation of groups)\&. .sp Note that \fBuseradd\fR will not create a home directory for such a user, regardless of the default setting in /etc/login\&.defs (\fBCREATE_HOME\fR)\&.

Valid default\-changing options are: .PP \fB\-b\fR, \fB\-\-base\-dir\fR\ \&\fIBASE_DIR\fR .RS 4 The path prefix for a new user\*(Aqs home directory\&. The user\*(Aqs name will be affixed to the end of \fIBASE_DIR\fR to form the new user\*(Aqs home directory name, if the \fB\-d\fR option is not used when creating a new account\&. .sp This option sets the \fBHOME\fR variable in /etc/default/useradd\&. .RE .PP \fB\-e\fR, \fB\-\-expiredate\fR\ \&\fIEXPIRE_DATE\fR .RS 4 das Datum, an dem das Benutzerkonto abgeschaltet wird .sp This option sets the \fBEXPIRE\fR variable in /etc/default/useradd\&. .RE .PP \fB\-f\fR, \fB\-\-inactive\fR\ \&\fIINACTIVE\fR .RS 4 die Anzahl von Tagen nach dem Ablaufen des Passworts bis das Konto deaktiviert wird .sp This option sets the \fBINACTIVE\fR variable in /etc/default/useradd\&. .RE .PP \fB\-g\fR, \fB\-\-gid\fR\ \&\fIGROUP\fR .RS 4 The group name or ID for a new user\*(Aqs initial group (when the \fB\-N/\-\-no\-user\-group\fR is used or when the \fBUSERGROUPS_ENAB\fR variable is set to \fIno\fR in /etc/login\&.defs)\&.

Dies muss auf dem entsprechenden Server durchgef\(:uhrt werden\&. .PP Similarly, if the username already exists in an external user database such as NIS or LDAP, \fBuseradd\fR will deny the user account creation request\&. .PP It is usually recommended to only use usernames 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 usernames 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\&.)\&.
