Timer with sound alarm

sleep 15m; yes > /dev/dsp
Just replace 15m with desired time. no suffix or 's' for seconds; 'h' for hours You need to be root or in audio group to write to /dev/dsp. You may use yes | head -n 2000 for about 1 second beep. Wrote this as echo -e '\a' not always works as desired (ex. visual bell)

What? This clobbers /dev/dsp and I have to recreate it. This is malicious.

There is no such device.

if there is no such device, you are not using OSS. you can try using "speaker-test -t sine -c 1" instead of "yes > /dev/dsp"

It also requires root. It also ignores the fact OSS is obsolete.

you can actually use /dev/dsp with alsa-oss package and there's no need for the obsolete OSS. It is also no need to be root, if you are in "audio" group
