Команда rtcwake: опции, ключи и примеры использования

rtcwake

Enter a system sleep state until specified wakeup time relative to your bios clock.

  • Show whether an alarm is set or not:

sudo rtcwake -m show -v

  • Suspend to ram and wakeup after 10 seconds:

sudo rtcwake -m mem -s {{10}}

  • Suspend to disk (higher power saving) and wakeup 15 minutes later:

sudo rtcwake -m disk --date +{{15}}min

  • Freeze the system (more efficient than suspend-to-ram but linux > 3.9 required) and wakeup at a given date and time:

sudo rtcwake -m freeze --date {{YYYYMMDDhhmm}}

  • Disable a previously set alarm:

sudo rtcwake -m disable

  • Perform a dry run to wakeup the computer at a given time. (Press Ctrl + C to abort):

sudo rtcwake -m on --date {{hh:ss}}
