.SH DESCRIPTION
|
|
|
|
|
\fBlastlog\fR formats and prints the contents of the last login log,
|
|
|
|
|
\fI/var/log/lastlog\fR. The \fBlogin-name\fR, \fBport\fR, and \fBlast login
|
|
|
|
|
time\fR will be printed.
|
2007-10-07 17:14:14 +05:30
|
|
|
The default (no flags) causes lastlog entries to be printed, sorted
|
|
|
|
|
by the numerical UID.
|
2007-10-07 17:14:02 +05:30
|
|
|
Entering \fB-u \fIlogin-name\fR flag will
|
|
|
|
|
cause the lastlog record for \fIlogin-name\fR only to be printed.
|
|
|
|
|
Entering \fB-t \fIdays\fR will cause only the
|
|
|
|
|
lastlogins more recent than \fIdays\fR to be printed.
|
|
|
|
|
The \fB-t\fR flag overrides the use of \fB-u\fR.
|
|
|
|
|
.PP
|
|
|
|
|
If the user has never logged in the message \fB"**Never logged in**"\fR will
|
|
|
|
|
be displayed instead of the port and time.

.SH CAVEATS
|
|
|
|
|
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).
