NAME
       chklastlog - check lastlog-file for deleted entries

SYNOPSIS
       chklastlog

DESCRIPTION
       Chklastlog  is  reading all entries from the file /var/log/wtmp (file with informations about logins and logouts) and checks for every user
       found in this file whether there is an entry in the file /var/log/lastlog, too. The program will complain about userids with logins but	no
       lastlogin information.

       To  run	chklastlog you need read permission on the files /var/log/wtmp and /var/log/lastlogin. Normally these files are world-readable and
       no special privileges are required to run the checker.

FILES
       /var/log/wtmp	   login data base
       /var/log/lastlog    last login times

SEE ALSO

LIMITATIONS
       This program only works if the user has not logged in after the deletion of their lastlog entry.

       This program was designed to run on SunOS 4.x systems only. On other systems the output is undefined...
