Name
ac - login accounting
Syntax
/etc/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...
Description
The command 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 is maintained by and 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 Specifies 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, is used.
