Every thing has the begining. In order to use my PC as an alarm clock, I wrote this script for playing my MP3 files. This is my first shell script. It's very simple but works fine. It just checks the directiory which includes MP3 files then plays all MP3 randomly.

#!/bin/bash
MUSICDIR=/Gaia/My\ Music/

echo "#### Start MP3 Alarm ####"

/bin/aumix-minimal -w 75

if [ -d "$MUSICDIR" ]; then
	/usr/bin/mpg123 -g 90 -z "$MUSICDIR"*.mp3
else	
	/bin/mount /Gaia
	/usr/bin/mpg123 -g 90 -z "$MUSICDIR"*.mp3
	/bin/umount /Gaia
fi
/bin/aumix-minimal -w 75

Here is another version which uses playlist file.

#!/bin/bash
PLAYLIST=/Gaia/morningcall.m3u

echo "#### Start MP3 Alarm ####"

/bin/aumix-minimal -w 75

if [ -e "$PLAYLIST" ]; then
	/usr/bin/mpg123 -g 90 -z -@ "$PLAYLIST"
else	
	/bin/mount /Gaia
	/usr/bin/mpg123 -g 90 -z -@ "$PLAYLIST"
	/bin/umount /Gaia
fi
/bin/aumix-minimal -w 75

Before using this script, we must generate playlist first.

/usr/bin/locate *.mp3 > morningcall.m3u

Make sure to run this script with root crontab and set the BIOS alarm boot time.
It might be 10 years ago that I wrote DOS batch file....... -----
