NAME
ac - login accounting
SYNOPSIS
/usr/sbin/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 pro- duced. -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 undis- turbed it will grow without bound, so periodically any information desired should be collected and the file truncated.
