|
.Sh SYNOPSIS
|
|
.Nm ac

|
.\".Op Fl c Ar console
|
|
.Op Fl t Ar tty
|
|
.Op Fl w Ar wtmp
|
|
.Op Ar users ...
|
|
.Sh DESCRIPTION
|
|
If the file
|
|
.Pa /var/log/wtmp
|
|
exists, a record of individual login and logout
|
|
times are written to it by
|
|
.Xr login 8
|
|
and
|
|
.Xr init 8 ,
|
|
respectively.
|
|
.Nm \&Ac
|
|
examines these records and writes the accumulated connect time
|
|
for all logins to the standard output.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indentXXX
|
|
.It Fl d
|
|
Display the connect times in 24 hour chunks.
|
|
.\" .It Fl c Ar console
|
|
.\" Use
|
|
.\" .Ar console
|
|
.\" as the name of the device that local X sessions (ut_host of ":0.0")
|
|
.\" originate from. If any login has been recorded on
|
|
.\" .Ar console
|
|
.\" then these X sessions are ignored unless COMPAT_SUNOS was defined at
|
|
.\" compile time.
|
|
.It Fl p
|
|
Print individual users' totals.
|
|
.It Fl t Ar tty
|
|
Only do accounting logins on certain ttys. The
|
|
.Ar tty
|
|
specification can start with '!' to indicate not this
|
|
.Ar tty
|
|
and end with '*' to indicate all similarly named ttys.
|
|
Multiple
|
|
.Fl t
|
|
flags may be specified.
|
|
.It Fl w Ar wtmp
|
|
Read connect time data from
|
|
.Ar wtmp
|
|
instead of the default file,
|
|
.Pa /var/log/wtmp .
|
|
.It Ar users ...
|
|
Display totals for the given individuals only.
|
|
.El
|
|
.Pp
|
|
If no arguments are given,
|
|
.Nm ac
|
|
displays the total connect time for all
|
|
accounts with login sessions recorded in
|
|
.Pa wtmp .
|
|
.Pp
|
|
The default
|
|
.Pa wtmp
|
|
file will increase without bound unless it is truncated.
|
|
It is normally truncated by the daily scripts run
|
|
by
|
|
.Xr cron 8 ,
|
|
which rename and rotate the
|
|
.Pa wtmp
|
|
files, keeping a week's worth of data on
|
|
hand. No login or connect time accounting is performed if
|
|
.Pa /var/log/wtmp
|
|
does not exist.
|
|
.Pp
|
|
For example,
|
|
.Bd -literal -offset
|
|
ac -p -t "ttyd*" > modems
|
|
ac -p -t "!ttyd*" > other
|
|
.Ed
|
|
.Pp
|
|
allows times recorded in
|
|
.Pa modems
|
|
to be charged out at a different rate than
|
|
.Pa other .
|
|
.Pp
|
|
The
|
|
.Nm ac
|
|
utility exits 0 on success, and >0 if a fatal error occurs.

.\" .Sh NOTES
|
|
.\" If COMPAT_SUNOS is defined
|
|
.\" .Nm ac
|
|
.\" ignores the fact that entries with ut_host of ":0.0" are not real
|
|
.\" login sessions. Normally such entries are ignored except in the case
|
|
.\" of a user being logged in when the
|
|
.\" .Pa wtmp
|
|
.\" file was rotated, in which case a login with ut_host of ":0.0" may
|
|
.\" appear without any preceeding console logins.
|
|
.\" If no one is logged in on the console, the user is deemed to have
|
|
.\" logged in on at the earliest time stamp found in
|
|
.\" .Pa wtmp .
|
|
.\" Use of
|
|
.\" .Pa console
|
|
.\" allows
|
|
.\" .Nm ac
|
|
.\" to identify and correcty process a logout for the user. The default
|
|
.\" value for
|
|
.\" .Pa console
|
|
.\" is usually correct at compile time.
