Smoke.sh is just a batch script that runs the beep command multiple<br>
times and pauses inbetween beeps. Command arguments for beep command<br>
are -f (frequency) and -l (length in milliseconds)<br>
<br>
while true #loop forever<br>
if `vmstat|tail -1|cut -d\" \" -f2`.to_i > 2 #vmstat dumps system<br>
info, the rest formats it to get just the processor queue. "If queue ><br>
2"<br>
system("beep -f " + (200+rand(400)).to_s + " -l 150") #runs beep<br>
command with a random frequency between 200-600hz for 150ms.<br>
end<br>
end<br>
<br>
To end program, do pkill ruby or ctrl-c. Program is ran by "$ruby wopr.rb"<br>
