Sleep_Until.sh - YAD GUI for RTCWake: Make your computer sleep and wake up at a given time

by Jorge A. Duarte

SleepUntil is a bash script, which makes use of YAD to capture data for rtcwake through a GUI Dialog. Through rtcwake the OS sleeps, and wakes up at a given time (today or tomorrow).

$ sudo apt-get install yad

Hardware Clock:

• Hardware clock must be set to UTC. If not, the script must be edited (remove the -u flag from rtcwake):

[FILE: sleep_until.sh]
...
# replace "sudo rtcwake -m mem -u -t $(date +%s -d "$foo")" for:
sudo rtcwake -m mem -t $(date +%s -d "$foo")
...
