I do quite a few OpenEmbedded project builds during the course of a week. This process usually takes 3-5 minutes. That is just enough time to get distracted doing something else and forget about the build until an hour later when you realize — oops, I was supposed to send out a release email once the build was finished and uploaded. It occured to me that it would be nice if my computer played a distinct sound at the end of the build. With Linux this is incredibly easy:
- wget http://upload.wikimedia.org/wikipedia/commons/7/76/Ding_Dong_Bell.ogg
- sudo mv Ding_Dong_Bell.ogg /usr/local/
- sudo aptitude install cplay
- sudo echo “cplay /usr/local/Ding_Dong_Bell.ogg” > /usr/local/bin/bell
- sudo chmod 775 /usr/local/bin/bell
Now, when I have a long build, I simply do something like:
bitbake my-image; bell
There is probably something better than cplay that does not start a UI — any suggestions?
Funny, I do similar things for writing a rootfs to my SD card.
jconnolly@jconnolly-linux:/tmp$ cat `which writebug.sh`
# Make sure only root can run our script
if [[ $EUID -ne 0 ]]; then
echo “This script must be run as root” 1>&2
if [ $# -ne $EXPECTED_ARGS ]
echo “Usage: `basename $0` image-file partition”
dd if=$1 of=$2
e2fsck -f -y $2
beep -f 450 -l 50 -r 3
notify-send “writebug.sh done”

tried mplayer, seems a little more friendly than cplay for this application — thanks.
