+.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 "OPZIONI"
+.PP

+.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

+/home
+by default\&.
+.RE
+.PP
+\fB\-c\fR, \fB\-\-comment\fR\ \&\fICOMMENT\fR

+.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

+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

+.RE
+.PP
+\fB\-f\fR, \fB\-\-inactive\fR\ \&\fIINACTIVE\fR
+.RS 4
+Il numero di giorni dopo la scadenza della password prima che l\*(Aqaccount venga permanentemente disabilitato\&. Un valore pari a 0 disabilita l\*(Aqaccount non appena la password \(`e scaduta, ed un valore pari a \-1 disabilita questa funzionalit\(`a\&.
+.sp
+If not specified,

+.RE
+.PP
+\fB\-g\fR, \fB\-\-gid\fR\ \&\fIGROUP\fR

+.sp
+If not specified, the behavior of
+\fBuseradd\fR
+will depend on the

+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
