The users can be specified by a login name, a numerical user ID,

<title>NOTE</title>
<para>
The <filename>lastlog</filename> 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 "<command>ls -l</command>" (which can indicate a really big file if
you have in <filename>passwd</filename> users with a high UID). You can
display its real size with "<command>ls -s</command>".
</para>

<refsect1 id='configuration'>
<title>CONFIGURATION</title>
<para>
The following configuration variables in
<filename>/etc/login.defs</filename> change the behavior of this
tool:

<variablelist>
&LASTLOG_UID_MAX;

<refsect1 id='files'>

<title>CAVEATS</title>
<para>
Large gaps in UID numbers will cause the lastlog program to run
longer with no output to the screen (i.e. if in lastlog database there
is no entries for users with UID between 170 and 800 lastlog will appear
to hang as it processes entries with UIDs 171-799).
