|
|
.Nm
|
|
.Op Fl d | p
|
|
.Op Fl t Ar tty

|

|
|
.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 1
|
|
and
|
|
.Xr init 8 ,
|
|
respectively.
|
|
The program
|
|
.Nm
|
|
examines these
|
|
records and writes the accumulated connect time for all logins to the
|
|
standard output.
|
|
.Pp
|
|
Options available:
|
|
.Bl -tag -width indentXXX
|
|
.It Fl d
|
|
Display the connect times in 24 hour chunks.
|
|
.It Fl p
|
|
Display individual user totals.
|
|
.It Fl t Ar tty
|
|
Only do accounting logins on certain ttys. The
|
|
.Ar tty
|
|
specification can start with
|
|
.Ql !
|
|
to indicate not this
|
|
.Ar tty
|
|
and end with
|
|
.Ql *
|
|
to indicate all similarly named ttys.
|
|
Multiple
|
|
.Fl t
|
|
flags may be specified.
|
|
.It Fl w Ar file
|
|
Read raw connect time data from
|
|
.Ar file
|
|
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
|
|
displays the total amount of login time for all active accounts on the
|
|
system.
|
|
.Pp
|
|
The default
|
|
.Pa wtmp
|
|
file is an infinitely increasing file
|
|
unless frequently truncated. This is normally
|
|
done by the daily daemon scripts scheduled by
|
|
.Xr cron 8 ,
|
|
which rename and rotate the
|
|
.Pa wtmp
|
|
files before truncating them (and keep about a week's worth on hand).
|
|
No login times are collected, however, if the file 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
|
|
utility exits 0 on success, and >0 if a fatal error occurs.
