AC(8)                   GENIX Programmer's Manual                   AC(8)



      NAME
           ac - login accounting

      SYNOPSIS
           /etc/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...

      DESCRIPTION
           Ac produces a printout giving connect time for  each  user  who  has
           logged in during the life of the current wtmp file.  A total is also
           produced.  -w is used to specify an alternate wtmp file.  -p  prints
           individual totals; without this option, only totals are printed.  -d
           causes a printout for each midnight to midnight period.  Any  people
           will  limit  the  printout to only the specified login names.  If no
           wtmp file is given, /usr/adm/wtmp is used.

           The accounting file /usr/adm/wtmp is maintained by init  and  login.
           Neither  of these programs creates the file, so if it does not exist
           no connect-time accounting is done.  To start accounting, it  should
           be  created  with  length  0.  On the other hand if the file is left
           undisturbed it will grow without bound, so periodically any informa-
           tion desired should be collected and the file truncated.

      FILES
           /usr/adm/wtmp
