.SH "SYNOPSIS"
.HP 8
\fBlastlog\fR [\fIoptions\fR]
.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 a high UID). You can display its real size with 
\fBls \-s\fR.
.SH "FILES"
.TP

.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).
