Author: yar Date: Wed Nov 24 00:05:19 2010 New Revision: 215786 URL: http://svn.freebsd.org/changeset/base/215786 Log: Clarify a few details about iostat(8) behavior: - The default repeat count for iostat(8) is 1 unless there was a -w on the command line. - A -x display doesn't include TTY or CPU stats by default but they can be turned on with a -T or -C, respectively.
