This \fIRANGE\fR of users can be specified with a min and max values (\fIUID_MIN\-UID_MAX\fR), a max value (\fI\-UID_MAX\fR), or a min value (\fIUID_MIN\-\fR)\&. .RE .PP When none of the \fB\-l\fR, \fB\-m\fR, or \fB\-r\fR options are used, \fBfaillog\fR displays the faillog record of the specified user(s)\&. .SH "AVVISI/CAVEAT" .PP \fBfaillog\fR only prints out users with no successful login since the last failure\&. To print out a user who has had a successful login since their last failure, you must explicitly request the user with the \fB\-u\fR flag, or print out all users with the \fB\-a\fR flag\&. .SH "FILE" .PP /var/log/faillog .RS 4 File per tracciare gli accessi falliti\&. .RE .SH "VEDERE ANCHE" .PP \fBlogin\fR(1), \fBfaillog\fR(5)\&.
