+.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
+The following configuration variables in
+/etc/login\&.defs
+change the behavior of this tool:
+.PP
+\fBENV_HZ\fR (string)
+.RS 4
+If set, it will be used to define the HZ environment variable when a user login\&. The value must be preceded by
+\fIHZ=\fR\&. A common value on Linux is
+\fIHZ=100\fR\&.
+.RE
+.PP
+\fBENV_TZ\fR (string)
+.RS 4
+If set, it will be used to define the TZ environment variable when a user login\&. The value can be the name of a timezone preceded by
+\fITZ=\fR
+(for example
+\fITZ=CST6CDT\fR), or the full path to the file containing the timezone specification (for example
+/etc/tzname)\&.
+.sp
+If a full path is specified but the file does not exist or cannot be read, the default is to use
+\fITZ=CST6CDT\fR\&.
+.RE
+.SH "FILE"
+.PP
+/etc/passwd
+.RS 4
+Informazioni sugli account utente\&.
+.RE
+.PP
+/etc/shadow
+.RS 4
+Informazioni sicure sugli account utente\&.
