158 Periodic output goes to stdout, by default, unless --out is used to specify an output file.

276 For interval-mode, turbostat will immediately end the current interval
278 turbostat will then start the next interval.
279 Control-C will be send a SIGINT to turbostat,
283 SIGINT will interrupt interval-mode.
284 The end-of-interval data will be collected and displayed before turbostat exits.
286 SIGUSR1 will end current interval,
287 end-of-interval data will be collected and displayed before turbostat
288 starts a new interval.
