Author: araujo Date: Tue Aug 21 11:22:49 2018 New Revision: 338133 URL: https://svnweb.freebsd.org/changeset/base/338133 Log: - Add CSV output to gstat via -C flag. Add a -C option, similar to -B, that allows gstat to produce basic CSV output with absolute timestamps (ISO 8601, nearly.) Multiple devices are handled by way of a single-pivot CSV table with duplicated timestamps for each object output.
