.SH "DESCRIPTION"

.PP
\fBlastlog\fR formats and prints the contents of the last login log \fI/var/log/lastlog\fR file\&. The \fI login\-name\fR, \fIport\fR, and \fIlast login time\fR will be printed\&. The default (no flags) causes lastlog entries to be printed, sorted by their order in \fI/etc/passwd\fR\&.

.SH "OPTIONS"

.TP
The options which apply to the \fBlastlog\fR command are:
.TP
\fB\-h\fR, \fB\-\-help\fR
Print help message and exit\&.

.TP
\fB\-t\fR, \fB\-\-time\fR \fIDAYS\fR
Print the lastlog records more recent than \fIDAYS\fR\&.

.TP
\fB\-u\fR, \fB\-\-user\fR \fILOGIN\fR
Print the lastlog record for user with specified \fILOGIN\fR only\&.

.TP
The \fB\-t\fR flag overrides the use of \fB\-u\fR\&.


.PP
If the user has never logged in the message \fI **Never logged in**\fR will be displayed instead of the port and time\&.

.SH "NOTE"

.PP
The \fBlastlog\fR file is a database which contains info on the last login of each user\&. You should not rotate it\&. It is a sparse file, so its size on the disk is much smaller than the one shown by \fBls \-l\fR (which can indicate a really big file if you have an high UID)\&. You can display its real size with \fBls \-s\fR\&.

.SH "FILES"

.TP
\fI/var/log/lastlog\fR
lastlog logging file
.SH "CAVEATS"

.PP
Large gaps in uid numbers will cause the lastlog program to run longer with no output to the screen (i\&.e\&. if mmdf=800 and last uid=170, program will appear to hang as it processes uid 171\-799)\&.
