+.PP
+The
+\fBnewusers\fR
+command reads a
+\fIfile\fR
+(or the standard input by default) and uses this information to update a set of existing users or to create new users\&. Each line is in the same format as the standard password file (see
+\fBpasswd\fR(5)) with the exceptions explained below:

+pw_name:pw_passwd:pw_uid:pw_gid:pw_gecos:pw_dir:pw_shell
+.PP
+\fIpw_name\fR
+.RS 4
+Il nome dell\*(Aqutente\&.
+.sp
+It can be the name of a new user or the name of an existing user (or a user created before by
+\fBnewusers\fR)\&. In case of an existing user, the user\*(Aqs information will be changed, otherwise a new user will be created\&.

+If this field contains the name of an existing group (or a group created before by
+\fBnewusers\fR), the GID of this group will be used as the primary group ID for the user\&.

+.PP
+The options which apply to the
+\fBnewusers\fR
+command are:

+.RE
+.PP

+.PP
+\fB\-r\fR, \fB\-\-system\fR

+Crea un account di sistema\&.
+.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
+login\&.defs, instead of
+\fBUID_MIN\fR\-\fBUID_MAX\fR
+(and their
+\fBGID\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\-s\fR, \fB\-\-sha\-rounds\fR
+.RS 4
+Usa il numero specificato di cicli per cifrare la password\&.
+.sp
+Il valore 0 indica che il sistema utilizzer\(`a il numero predefinito di cicli per il metodo crypt (5000)\&.
+.sp
+I valori minimo di 1\&.000 e massimo di 999\&.999\&.999 sono forzati\&.
+.sp
+Si pu\(`o utilizzare questa opzione solo con i metodi di cifratura SHA256 o SHA512\&.
+.sp
+By default, the number of rounds is defined by the SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS variables in
+/etc/login\&.defs\&.

+.SH "CONFIGURAZIONE"
+.PP
+The following configuration variables in
+/etc/login\&.defs
+change the behavior of this tool:
+.PP
+\fBENCRYPT_METHOD\fR (string)
+.RS 4
+Definisce l\*(Aqalgoritmo di cifratura predefinito per le password (se non ne viene specificato uno a riga di comando)\&.
+.sp
+It can take one of these values:
+\fIDES\fR

+\fIMD5\fR, \fISHA256\fR, \fISHA512\fR\&.
+.sp
+Note: this parameter overrides the
+\fBMD5_CRYPT_ENAB\fR
+variable\&.
+.RE
+.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
+\fBHOME_MODE\fR (number)
+.RS 4
+The mode for new home directories\&. If not specified, the
+\fBUMASK\fR
+is used to create the mode\&.
+.sp
+\fBuseradd\fR
+and
+\fBnewusers\fR
+use this to set the mode of the home directory they create\&.
+.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
+Il valore predefinito \(`e 0, che non pone nessun limite al numero di membri per gruppo\&.
+.sp
+Questa opzione (dividi gruppo) permette di limitare la lunghezza delle righe nel file \(Fogroup\(Fc\&. Questo \(`e utile per essere certi che le righe per gruppi NIS non eccedano i 1024 caratteri\&.
+.sp
+Se si deve impostare questo limite, si pu\(`o usare 25\&.
+.sp
+Nota: la divisione dei gruppi potrebbe non essere supportata da ogni strumento (anche all\*(Aqinterno del pacchetto Shadow)\&. Non si dovrebbe utilizzare questa variabile a meno di esserci forzati\&.
+.RE
+.PP
+\fBMD5_CRYPT_ENAB\fR (boolean)
+.RS 4
+Indicate if passwords must be encrypted using the MD5\-based algorithm\&. If set to
+\fIyes\fR, new passwords will be encrypted using the MD5\-based algorithm compatible with the one used by recent releases of FreeBSD\&. It supports passwords of unlimited length and longer salt strings\&. Set to
+\fIno\fR
+if you need to copy encrypted passwords to other systems which don\*(Aqt understand the new algorithm\&. Default is
+\fIno\fR\&.
+.sp
+This variable is superseded by the
+\fBENCRYPT_METHOD\fR
+variable or by any command line option used to configure the encryption algorithm\&.
+.sp
+This variable is deprecated\&. You should use
+\fBENCRYPT_METHOD\fR\&.
+.RE
+.PP
+\fBPASS_MAX_DAYS\fR (number)
+.RS 4
+Il numero massimo di giorni che una password pu\(`o essere utilizzata\&. Se la password \(`e pi\(`u vecchia verr\(`a imposto il suo cambiamento\&. Se non specificato viene assunto \-1 (che disabilita questo controllo)\&.
+.RE
+.PP
+\fBPASS_MIN_DAYS\fR (number)
+.RS 4
+Il numero minimo di giorni tra due cambiamenti di password\&. Ogni tentativo di cambiare la password prima di questo periodo verr\(`a rifiutato\&. Se non specificato viene assunto \-1 (che disabilita questo controllo)\&.
+.RE
+.PP
+\fBPASS_WARN_AGE\fR (number)
+.RS 4
+Il numero di giorni per i quali un utente va avvisato che la sua password sta per scadere\&. Se zero l\*(Aqutente viene avvisato solo alla scadenza\&. Un valore negativo indica che non si deve avvisare mai\&. Se non specificato allora non c\*(Aq\(`e nessun avviso\&.
+.RE
+.PP
+\fBSHA_CRYPT_MIN_ROUNDS\fR (number), \fBSHA_CRYPT_MAX_ROUNDS\fR (number)
+.RS 4
+When
+\fBENCRYPT_METHOD\fR
+is set to
+\fISHA256\fR
+or
+\fISHA512\fR, this defines the number of SHA rounds used by the encryption algorithm by default (when the number of rounds is not specified on the command line)\&.
+.sp
+Con molti cicli \(`e pi\(`u difficile trovare una password usando la forza bruta\&. Ma va notato che \(`e richiesta maggiore potenza di calcolo per autenticare gli utenti\&.
+.sp
+Se non specificato sar\(`a la libc a scegliere il numero di cicli (5000)\&.
+.sp
+Il valore deve essere compreso tra 1\&.000 e 999\&.999\&.999\&.
+.sp
+If only one of the
+\fBSHA_CRYPT_MIN_ROUNDS\fR
+or
+\fBSHA_CRYPT_MAX_ROUNDS\fR
+values is set, then this value will be used\&.
