linux alarm clock

I have too used to alarm clock, to wake me up every early morning. I set my alarm on my cellphone every night before I going to sleep. But recently, a simple stupid idea of creating an alarm clock in Linux comes to my mind.
I usually turns on my laptop overnight for some downloads, system updates. It is a basic requirement for a linux alarm clock. This example is a bit creepy, i know. But somehow it works.
First you need to calculate what time you wanna wake up? Let say if you wanna wake up after 5 hour and 30 minutes. You need to calculate the time in seconds using bc and parse the result to sleep, and later play a song to wakes you up after the sleep:
sleep `echo "60*60*5+60*30" | bc`; xmms -pYou can preloaded with any song and set your preferred volume.
The better and easy way should be using at or crontab. I have tried but it doesn’t seems to be working.
Such as ….
at 2:10 <<< "xmms -p"or crontab
crontab -eand write a line in
45 7 * * * /usr/bin/xmms -pI have no idea why it fails :(

btw .. the crontab hack worked for me .. (you’ll need xmms running first of course)

cool, the xmms-alarm is at my apt repo. Nice with complete function. Did I need to make XMMS running too?
I try at terminal, execute xmms -p will open the xmms + play, donno why it doesn’t happen to at and crontab.

You don’t need xmms runing, only an X server.
xmms needs an X server to work.

This worked for me:
> echo “DISPLAY=:0 xmms -p” | at 09:33

Been trying the crontab alarm clock idea for a while for a while; it might be it doesn’t work because it runs it in the background? Dunno…
