AC(8)                       System Manager's Manual                      AC(8)



NAME
       ac - login accounting

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

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.

       The  accounting  file  /var/adm/wtmp  is  maintained  by  init(8)   and
       login(1).   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 information
       desired should be collected and the file truncated.

OPTIONS
       -w wtmp
              Specify an alternate wtmp file.

       -p     Print  individual  totals;  without this option, only totals are
              printed.

       -d     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, /var/adm/wtmp is used.

FILES
       /var/adm/wtmp
