.Sh HISTORY
|
|
|
|
|
A
|
|
|
|
|
.Nm
|
|
|
|
|
utility appeared in
|
|
|
|
|
.Fx 5.0 .
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
utility only works interactively.
|
|
|
|
|
It should probably detect when it is run non-interactively and produce
|
|
|
|
|
simple
|
|
|
|
|
.Tn ASCII
|
|
|
|
|
text output.
|
|
|
|
|
Otherwise, this utility should probably be folded into
|
|
|
|
|
.Xr systat 1
|
|
|
|
|
which only works interactively and is the obvious utility to run for
|
|
|
|
|
various other forms of system statistics.
