|
.PP
|
|
The
|
|
lastlog
|
|
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 usually much smaller than the one shown by "\fBls \-l\fR" (which can indicate a really big file if you have in
|
|
passwd
|
|
users with a high UID)\&. You can display its real size with "\fBls \-s\fR"\&.
|
|
.SH "KONFIGURATION"

The following configuration variables in

.SH "WARNUNGEN"
|
|
.PP
|
|
Gro\(sse L\(:ucken in den Benutzerkennungen haben zur Folge, dass das Lastlog\-Programm l\(:angere Zeit nichts auf den Bildschirm ausgibt\&. Wenn sich z\&.B\&. in der Lastlog\-Datenbank kein Eintrag f\(:ur Benutzer mit der Kennung zwischen 170 und 800 befindet, wird es, w\(:ahrend der Verarbeitung der Eintr\(:age zu den Kennungen 171 bis 799, scheinen, als sei lastlog stehen geblieben\&.
|
|
.PP
|
|
Having high UIDs can create problems when handling the
|
|
/var/log/lastlog
|
|
with external tools\&. Although the actual file is sparse and does not use too much space, certain applications are not designed to identify sparse files by default and may require a specific option to handle them\&.
