Manual page for AC(8)
ac - login accounting
SYNOPSIS
/usr/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 information
desired should be collected and the file truncated.
FILES
/usr/adm/wtmp
