+.SH "DESCRIZIONE"
+.PP
+The
+\fBlogin\fR
+program is used to establish a new session with the system\&. It is normally invoked automatically by responding to the
+\fIlogin:\fR
+prompt on the user\*(Aqs terminal\&.
+\fBlogin\fR
+may be special to the shell and may not be invoked as a sub\-process\&. When called from a shell,
+\fBlogin\fR
+should be executed as
+\fBexec login\fR
+which will cause the user to exit from the current shell (and thus will prevent the new logged in user to return to the session of the caller)\&. Attempting to execute
+\fBlogin\fR
+from any shell but the login shell will produce an error message\&.
+.PP
+The user is then prompted for a password, where appropriate\&. Echoing is disabled to prevent revealing the password\&. Only a small number of password failures are permitted before
+\fBlogin\fR
+exits and the communications link is severed\&.
+.PP
+If password aging has been enabled for your account, you may be prompted for a new password before proceeding\&. You will be forced to provide your old password and the new password before continuing\&. Please refer to
+\fBpasswd\fR(1)
+for more information\&.
+.PP
+After a successful login, you will be informed of any system messages and the presence of mail\&. You may turn off the printing of the system message file,
+/etc/motd, by creating a zero\-length file
+\&.hushlogin
+in your login directory\&. The mail message will be one of "\fIYou have new mail\&.\fR", "\fIYou have mail\&.\fR", or "\fINo Mail\&.\fR" according to the condition of your mailbox\&.
+.PP
+Your user and group ID will be set according to their values in the
+/etc/passwd
+file\&. The value for
+\fB$HOME\fR,
+\fB$SHELL\fR,
+\fB$PATH\fR,
+\fB$LOGNAME\fR, and
+\fB$MAIL\fR
+are set according to the appropriate fields in the password entry\&. Ulimit, umask and nice values may also be set according to entries in the GECOS field\&.
+.PP
+On some installations, the environmental variable
+\fB$TERM\fR
+will be initialized to the terminal type on your tty line, as specified in
+/etc/ttytype\&.
+.PP
+Pu\(`o anche essere eseguito uno script di inizializzazione per il proprio interprete dei comandi\&. Fare riferimento alla relativa sezione di manuale per maggiori informazioni su questa funzione\&.
+.PP
+Un sottosistema di login \(`e indicato dalla presenza del carattere \(Fo*\(Fc all\*(Aqinizio della shell di login\&. La directory home impostata sar\(`a utilizzata come root di un nuovo file system al quale l\*(Aqutente accede\&.
+.PP
+The
+\fBlogin\fR
+program is NOT responsible for removing users from the utmp file\&. It is the responsibility of
+\fBgetty\fR(8)
+and
+\fBinit\fR(8)
+to clean up apparent ownership of a terminal session\&. If you use
+\fBlogin\fR
+from the shell prompt without
+\fBexec\fR, the user you use will continue to appear to be logged in even after you log out of the "subsession"\&.

+\fBexec\fR, the user you use will continue to appear to be logged in even after you log out of the "subsession"\&.
+.PP
+As with any program,
+\fBlogin\fR\*(Aqs appearance can be faked\&. If non\-trusted users have physical access to a machine, an attacker could use this to obtain the password of the next person coming to sit in front of the machine\&. Under Linux, the SAK mechanism can be used by users to initiate a trusted path and prevent this kind of attack\&.
