Timer with sound alarm

Terminal - Timer with sound alarm
sleep 15m; yes > /dev/dsp

Timer with sound alarm

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)


There are 10 alternatives - vote for the best!

Terminal - Alternatives
sleep 3s && espeak "wake up, you bastard" 2>/dev/null

Functions: sleep

I'd prefer this one, you have to install espeak to get this running

say(){ mplayer -user-agent Mozilla "http://translate.google.com/translate_tts?tl=en&q=$(echo $* | sed 's#\ #\+#g')" > /dev/null 2>&1 ; }; sleep 3s && say "wake up, you bastard"

Know a better way?

What others think

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

There is no such device.

Comment by fossilet 266 weeks and 4 days ago

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"

Comment by unixmonkey8161 266 weeks and 4 days ago

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 It also ignores the fact OSS is obsolete.

Comment by kaedenn 266 weeks and 2 days ago

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
