+.SH "NOME"
+sulogin \- Single\-user login
+.SH "SINTASSI"
+.PP
+\fBsulogin\fR
+[\fItty\-device\fR]
+.SH "DESCRIZIONE"
+.PP
+The
+\fBsulogin\fR
+command is invoked by
+\fBinit\fR
+prior to allowing the user access to the system when in single user mode\&. This feature may only be available on certain systems where
+\fBinit\fR
+has been modified accordingly, or where the
+/etc/inittab
+has an entry for a single user login\&.
+.PP
+The user is prompted
+.PP
+Type control\-d to proceed with normal startup, (or give root password for system maintenance):
+.PP
+Input and output will be performed with the standard file descriptors unless the optional device name argument is provided\&.
+.PP
+If the user enters the correct root password, a login session is initiated\&. When
+\fIEOF\fR
+is pressed instead, the system enters multi\-user mode\&.
+.PP
+After the user exits the single\-user shell, or presses
+\fIEOF\fR, the system begins the initialization process required to enter multi\-user mode\&.
+.SH "AVVISI/CAVEAT"
+.PP
+This command can only be used if
+\fBinit\fR
+has been modified to call
+\fBsulogin\fR
+instead of
+/bin/sh, or if the user has set the
+\fIinittab\fR
+to support a single user login\&. For example, the line:
+.PP
+co:s:respawn:/etc/sulogin /dev/console
+.PP
+should execute the sulogin command in single user mode\&.
+.PP
+As complete an environment as possible is created\&. However, various devices may be unmounted or uninitialized and many of the user commands may be unavailable or nonfunctional as a result\&.
+.SH "CONFIGURAZIONE"
+.PP
+Le seguenti variabili di configurazione in
+/etc/login\&.defs
+cambiano il comportamento di questo strumento:
+.PP
+\fBENV_HZ\fR (testo)
+.RS 4
+Se impostato viene utilizzato per definire il valore della variabile d\*(Aqambiente HZ al login dell\*(Aqutente\&. Il valore deve essere preceduto da
+\fIHZ=\fR\&. Un valore comune per Linux \(`e
+\fIHZ=100\fR\&.
+.RE
+.PP
+\fBENV_TZ\fR (testo)
+.RS 4
+Se impostato viene usato per definire la variabile d\*(Aqambiente TZ al login dell\*(Aqutente\&. Il valore pu\(`o essere il nome di una \(Fotimezone\(Fc preceduta da
+\fITZ=\fR
+(ad esempio
+\fITZ=CST6CDT\fR), o il percorso completo di un file che contenga la specifica della \(Fotimezone\(Fc (ad esempio
+/etc/tzname)\&.
+.sp
+Se viene specificato il percorso completo di un file che per\(`o non esiste o non pu\(`o essere letto, allora viene utilizzato il valore predefinito
+\fITZ=CST6CDT\fR\&.
