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.
