By default, a record of individual login and logout times are
recorded by login(1) and
init(8), respectively to
syslogd(8). The
ac
utility examines these records and writes the
accumulated connect time (in hours) for all logins to the standard
output.
The options are as follows:
-d
-p
-t
tty-t
flags may be specified.-w
wtmpIf no arguments are given, ac
displays the
total connect time for all accounts with login sessions recorded in
log(1).
The ac
utility exits 0 on success,
and >0 if an error occurs.
Allow times recorded in modems to be charged out at a different rate than other:
ac -p -t "ttyd*" > modems ac -p -t "!ttyd*" > other
log(1), login(1), getutxent(3), utmpx(5), launchd(8), sa(8), syslogd(8)
An ac
command appeared in
Version 5 AT&T UNIX. This version of
ac
was written for NetBSD
0.9A from the specification provided by various systems' manual
pages.
