Ideen und Skripte…
Sleeptimer, Alert_clock, lxAutostart sind nur einige Skripte, die ich mit Hilfe der PCLinuxOS-Gemeinschaft erstellt habe.
Alle Skripte benötigen YAD in der Version 0.15.

#!/bin/bash
#
# Alarm clock for PCLinuxOS
#
# Don't miss important times and events. Turn your computer 
# into the perfect wake up system. Set the alarm and get the 
# Pizza out of the oven in perfect time.
