Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Functions

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)

Alternatives

There is 1 alternative - vote for the best!

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

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?

If you can do better, submit your command here.

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 188 weeks 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 187 weeks and 6 days ago

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 It also ignores the fact OSS is obsolete.

Comment by kaedenn 187 weeks and 5 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
