- usage: rtcwake [-aluv] [-d FILE] [-m MODE] [-s SECS] [-t UNIX]
-
- Enter the given sleep state until the given time.
-
- -a RTC uses time specified in /etc/adjtime
- -d FILE Device to use (default /dev/rtc)
- -l RTC uses local time
- -m Mode (--list-modes to see those supported by your kernel):
- standby S1: default mem S3: suspend to RAM
- disk S4: suspend to disk off S5: power off
- disable Cancel current alarm freeze stop processes/processors
- no just set wakeup time on just poll RTC for alarm
- show just show current alarm
- -s SECS Wake SECS seconds from now
- -t UNIX Wake UNIX seconds from epoch
- -u RTC uses UTC
- -v Verbose
