>Description:
iostat(8) says:

-c    Repeat the display count times.  If no repeat count is specified,
      the default is infinity.

But if you try to run it without a repeat count:

% iostat -c
iostat: option requires an argument -- c
usage: iostat [-CdhIKoTxz?] [-c count] [-M core] [-n devs] [-N system]
	      [-t type,if,pass] [-w wait] [drives]
>How-To-Repeat:
%iostat -c
