.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 "НАСТРОЙКА"
|
||
.PP
|
||
The following configuration variables in
|
||
/etc/login\&.defs
|
||

|
||
.RE
|
||
.SH "ПРЕДОСТЕРЕЖЕНИЯ"
|
||
.PP
|
||
Большие промежутки в значениях идентификаторов пользователей приводят к тому, что программа некоторое время ничего не выводит на экран (то есть, если в базе данных lastlog нет пользователей с идентификаторами с 170 по 800, то во время обработки UID с 171 по 799 программа кажется повисшей)\&.
|
||
.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\&.
