NAME

       chklastlog - check lastlog-file for deleted entries

SYNOPSIS

       chklastlog

DESCRIPTION

       Chklastlog is reading all entries from the file /var/log/wtmp (file with information 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

       wtmp(4), who(1), last(1)

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...
